Remove vestiges of OLDCARD PC Card support. We haven't needed/used
this since 5.x.

As threatened a while ago, remove support for tape media. Reports vary
but most people believe it stopped working a while ago.

Remove sysinstall's ability to adjust the tape block size. Installs from
tape have been broken for quite a while, and I'll be removing the rest
of sysinstall's knowledge of tapes shortly. I'm doing this piece now
because I want to switch from gnu's cpio to bsdcpio being integrated
into the installation environment and bsdcpio doesn't seem to handle
block sizes at all.

Fix numerous warnings. Aside from menu items in system.c and menu.c
this now compiles on i386 with WARNS?= 3. Most of the fixes included
adding missing 'static' keywords to internal functions, using fully-defined
terminators in statically defined arrays of structs, and various
signed vs unsigned mismatches. Also G/C'd unused configSecurity()
function.

Various NFS-related bug fixes (mostly related to using variable_get()
instead of variable_cmp() to test boolean rc.conf variables).

The PCMCIA Standard dictates that those funny cards you insert into

Add a new variable 'skipPCCARD'. This variable will cause sysinstall

Since userconfig feature is implemented by tweaking variables (hint.*)

Back out rev 1.74. This functionality causes a panic on 4.4-RELEASE
floppies if you try to actually use it. This code will work fine if
you build and use sysinstall on a running system, since you have the
benefit of an installed termcap file. However, this code does not
work on an MFSROOT, where you must set the TERMCAP environment
variable properly. Unfortunately the quick fix of setting the TERMCAP
variable doesn't seem to fix the problem either. olgeni will add this
functionality back once it's been fully implemented (hopefully using
the working code in termcap.c).

Remove the bogus check against "none" for release names (which
really doesn't make any sense, what was I smoking) and allow
the more canonical usage of "any" for either side of the comparison
for release name or architecture (meaning you can also set CD_VERSION=any
in a cdrom.inf file to cause sysinstall to always match it and likewise
with the architecture, if specified).

Add an option to select the Fix-it tty. The current behavior is utterly
*useless* on serial consoled machines.

D'oh! Inserted a clear() in a *very* wrong place with my last commit.

Bah, I got the MFC and this commit backwards. :)

More cosmetic surgery and a nasty null pointer bug in index.c fixed.

Be paranoid about refreshing after an action.

Completely rip-out and redesign sysinstall's refresh model as well
as redoing all the menus to have proper, or at least non-hallucinogenic,
keyboard accelerators.

This requires my recent update to libdialog to work properly and will
probably also exhibit some other "interesting" behavior while the last
few missing screen clears are found (which is why I'm not going to MFC
immediately). At least now, however, sysinstall does not gratuitously
redraw random screens at the drop of a hat and drive serial console
installers out of their minds.

Oh crud, did I ever screw the pooch! Rather than sync this with -stable,
I backed-out the changes in -current and didn't touch stable at all (I
thought I had my patch order reversed, not what actually happened).
AIEEE! I can't even blame the crack for this one since I broke my
crack pipe a few weeks ago. I think sleep deprivation gets the blame
for this one.

Medal for noticing this one goes to: Jim Bloom <bloom@acm.org>

MFC: Catch 3.2-stable sysinstall up to 4.0-current level functionality,
bringing in DHCP support. The only thing I left out were Poul-Henning's
newfs changes since I'm not sure if he's brought the rest of that support
into -stable yet. If it turns out that this is the case, I'll MFC those
changes too.

$Id$ -> $FreeBSD$

Make the newfs parameters a global option.

The default is still "-b 8192 -f 1024" but my experiments show that
"-b 16384 -f 4096 -c 100" is a more sensible value for modern
disksizes.

Re-enable DHCP client support again (but optional and turned off by default
for the time being) for debugging purposes.

Fix bug in options selection.

Make saving kernel configuration info disable-able (may be useful in certain
situations).

o Make package matching for specific package loading use the Latest/
feature of packages now so that no version info is embedded.

o Add a default X desktop menu offering afterstep, enlightenment, KDE, GNOME
and Windowmaker desktops instead of the boring twm(1) based one if the
user so chooses. This will require a little testing.

Add an option for resetting and rescanning the probed device list, perhaps
to now detect that CD you just remembered to put in the drive or that
pccard NIC that you've inserted (anybody can put pccardd in an mfsroot image
now you know.. :)

Totally change the way variables are accounted for in sysinstall.
Now we know which variables are internal and which need to be
backed to /etc/rc.conf.site. rc.conf is not touched now.

Also kget kernel change information back properly and set up a loader.rc
file to use it.

Eliminate Samba configuration. Sorry, but this was another one of
those ideas that, like the Apache server setup, was well-intentioned
but doomed to fail in the face of change. That and the fact that it
shouldn't be part of the installation tool, it should be part of the
post-installation setup tool (which we need to write). Combining the
two utilities into one utility was my first conceptual mistake.

Apologies also to Coranth Gryphon, who worked hard on the Apache
and Samba server setup code. These features were quite useful
for awhile, if that's any consolation, I just simply had the wrong
ideas about where to put them. :-(

1. Add a noWarn flag so that scripts can turn warnings off.
2. If hostname not set from script, bring up interactive dialog anyway.

Actually, rethink last commit and simply remove the apache configuration
entirely, as promised earlier (it's outdated now and doesn't really belong
in sysinstall).

It's easier to go forwards than backwards with this, and the RELENG_2_1_0
sysinstall was already broken (I think there's a PR for this somewhere).
This will require some additional changes elsewhere, like bringing in pw.

OK, I've got two ideas to file in the "really seemed like a good idea
at the time, but on further reflection..." bucket with these changes.

1. Checking the media before frobbing the disks was a fine idea, and
I wish it could have worked, but that leads to a rather difficult
situation when you need to mount the media someplace and you're about
to:

a) Chroot away from your present root.
b) Newfs the root to be.

You're basically screwed since there's no place to stick the mount
point where it will be found following the newfs/chroot (and eliminating
the chroot in favor of just using the "root bias" feature would work
great for the distributions but not the pkg_add calls done by the
package installer).

2. Automatic timeout handling. I don't know why, but alarm() frequently
returns no residual even when the alarm didn't go off, which defies
the man page but hey, since when was that so unusual? Take out timeouts
but retain the code which temporarily replaces the SIGINT handler in
favor of a more media-specific handler. This way, at least, if it's hanging
you can at least whap it. I think the timeout code would have been losing
over *really slow* links anyway, so it's probably best that it go.

This should fix NFS, tape & CDROM installs again (serves me right for getting
complacent and using just the FTP installs in my testing).

This is a patch that makes some of the "partitions" --> "slice" to be
more consistant in our use of the terms for differentiation between PC
partitions and traditional BSD partitions.

Make the long-awaited change from $Id$ to $FreeBSD$

avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

1. Take out console setup in options now that Joerg has moved it into
the main menu.
2. Conditionalized a few small things which needed it.
3. Put PC98 X servers in their own menu, there are so many of them now.
4. Rampaged on the menus.c file in general, reformatting and cleaning up.

Joerg's changes to add screen font and screenmap setting.
Some changes of my own to make screen saver configuration a little
more sane, and also make it easier to get to the keyboard/screen
setup from the options menu.

More tweaks to FTP reselection code - allow "none" to stand for
"no specific release - use anything you can find"

Installation cleanup, round II.

Try to make screen update more efficient (less flickering) by more
judicious use of dialog_clear_norefresh().

A number of improvements in the way statistics are printed, add a "chroot"
option for installing distributions and/or packages to somewhere other than /,
say for a case where you're installing to an external disk on some other
machine's behalf. More miscellaneous fixes to various problems I stumbled
across while adding this stuff.

Fix even more lurking bogons - why do I never find these until the last
possible minute? :-)

Don't use some of the low-contrast text attributes I was using before - they
apparently look bad on some LCD screens. While I'm in there, tweak and adjust
a number of other minor interface details which have been bothering me for
awhile.

Implement selective text attributes for the syscons vty / vt100 emulator
selection since an attribute which looks good on a color console doesn't
necessarily look good in an xterm.

Put back some changes I inadvertantly spammed with a cvs update.

Some cosmetic changes:

Make "selection bar" inverse video white-on-blue on color screens to avoid
it getting muddled up with popup dialogs.

Do disk selection in a more friendly fashion (for one thing, allow a
drive to be de-selected again if you change your mind).

Add a few strategic screen-saves to prevent corruption of screen contents
(thanks, Michael Elbel!).

Quite a few changes:

1. Fix the last display bugs (I hope) by use of dialog rebuilds at stategic
points.
2. Clean up the distributions menus so that everybody (that's reasonable)
has All and Clear options for setting/clearing things en-masse.
3. Various attempts at display optimization.
4. Change the wording of the `Don't use Write!' dialogs to make them more
explicitly define when and when not to use the option.

Bring this into sync.

I still have a _very very annoying_ display bug which occurs when a menu
item causes a submenu to be displayed - the screen repaints for the original
menu (which is restored upon return from the submenu) are off by about 4
characters. I've tried restoring the screen, the cursor position, you name
it - same deal. Grrrr! This commit is my first step in trying to get someone
else to help me look into this one since I'm just tearing my hair out at this
point!

1. Update all the copyrights to delete useless clauses 3 and 4.
2. Change more of the menu code over to new system.
3. Streamline label editor.

Major surgery.

1. Use new dialog menu hacks (no strings, just arrays of dialogMenuItem structs)
so that I can create composite menus with radio/checkbox/... items in them,
removing some long-standing UI bogons in various menus. This work isn't
finished yet, but will be done in two phases. This is phase one.

2. Remove all the script installation stuff. I never got time to document it,
it was arcane and it just complicated much of the code. There are better
ways of doing this if I want to do auto-driven installations later.

3. Remove much dead code and otherwise attempt to remove as much historical
grot as possible so that this code is easier to hack on. This is also
a two-stage process, phase one of which is now complete.

Clean up the options screen a little bit by shortening it by one line
in the vertical axis.

Make the editor a selectable option. Some people don't care for `ee'!

Major enhancements to the package adder (next step is to use the new dialog
functions to make the menus far less klunky, but one thing at a time).

Fix bug that had debug output spewing uselessly on vty2 when running multiuser.

Small tweaks to the presentation of this stuff.

Some general fixes for the package menu (still need to fix the "more than 10
items checked bug though). Now allow user to specify a PKG_TMPDIR. If
not selected, we try to make one.

Lots-o-cleanup(tm):

1. Fix the bogon I introduced that made some root filesystems fail to be
made with `unable to make filesystem on sd1s1a' or some such error
message.

2. Latest installment in the never-ending chapter on making FTP do the right
thing on a cruel internet.

3. Make `express install' a truly express install and split off what it used
to do into a `novice install' that's even more geared to the novice
by asking questions in order, rather than forcing them through the menu
interface.

4. Make anonymous FTP setup truly DTRT.

5. Build lndir directly into sysinstall and make the novice install offer
to set up the ports tree. Also make the ports setup truly explanatory
about what it's doing, and always link the ports destination to /usr/ports
if necessary so that bsd.port.mk doesn't need to be tweaked.

Sync up for this snapshot.

o Fix installUpgrade to start the holographic shell as well.
o Lots of documentation fixes.
o Rename FTP active to "FTP" and explain passive mode better.
o Make tcpip screen a bit more friendly.
o Literally dozens of nits.

Style police throughout.
Fix the ppp startup code.
Make the disklabel and fdisk screens "automatable"

Make all FTP failures "bounce" the connection properly.

Fix a couple of things I broke while fixing them.

1. Of course, the day after you roll the snapshots is the day you realize
that the FTP install doesn't deal with timeouts and hasn't since it was
written. Fixed.

2. Totally eliminate the OptionFlags. I only had to work harder to
sync them with configuration variables, so why not simply always use
configuration variables? This has actually greatly simplified areas
of the code.

Sync for Westhill build.

Fix fix.

More bug fixing, make debug settable two ways, put more meat into
the upgrade.

Too many bugs fixed to mention. This code just seems to BREED them.
Many interfaces were also simplified or generally cleaned up in an
attempt to curb this problem.

Sync.

Sync with today's sources:

o Implement the 2.0.5->2.1 upgrade procedure (gah).
o Bring in Coranth's support for configuration of anon ftp and Samba
plus some changes of my own.
o More attempts to actually write the documentation in english.
o Update docs to contain more 2.1-centric information.

Some rethinks on the way the attribute interface worked (now that
I'm really, truly using it). Allow distribution fetch to get .info
files from the root.flp OR the distribution in question, allowing us
to add flexibility to the scheme. At some point, perhaps soon, the
cached copy should probably go away entirely!

Almost snapshot time..
Merge today's work.

Add fuller debugging support to all device I/O routines.

Sync with my development sources, smashing an annoying bug and making
the options editor a little less pathological.

Tweak a message to be a bit more clear.
Declare missing fd.
Fix options bug where old text was still weird shades of blue when you came back.

Whole mass of changes from first code review. Eliminate some
long-standing bogons, try to make things more fault tolerant
in general, bring in the first version of my new package installation
menu.

Properly repaint an option in reverse video after changing its value.

Make descriptions stand-out a bit more.

General cleanup - sanitize use of variables.
Do more rational things in a number of other instances.

o Search much more aggressively for distributions in all extraction
methods. This should make the process rather more robust in the face
of entropy.
o Let tape cpio extract guess type of tape format.
o Hide cursor better in options screen.

Make the release name to load a configurable parameter.
Don't gratuitously shutdown network after NFS or FTP install.
Centralize release version string to one location included by everyone.
Bring in new options screen.
