- Akin r302691 in head, synchronize the build stripping for the disc1
image with that of the bootonly image (but similarly modulo games
and groff(1)) as the amd64 disc1 image is overflowing. This also
removes the defunct WITHOUT_ATF.
- Remove the misspelled WITHOUT_INSTALLIB (also in place with correct
spelling, i. e. WITHOUT_INSTALLLIB) from the bootonly image build
stripping.

This is a direct commit to stable/10 as the corresponding knobs have
different names in head and counterparts to e. g. MK_DEBUG_FILES and
MK_TESTS default to off in stable/10 in the first place.

Add primitive (untested) PowerPC/PowerPC64 VM image support.

Note: As it is currently written, the /boot/pmbr and

doesn't exist when we're running this.

Unmount filesystems before attempting to destroy the md which

Unmount filesystem and destroy md before we read the vnode from

Add NOSWAP option which can be set by a vmimage.conf file to specify

VM_EXTRA_PACKAGES is empty.

In vm_extra_pre_umount(), cleanup downloaded packages if pkg(8) was

Move resolv.conf(5) removal back to vm_extra_pre_umount() where it

The GCE image needs resolv.conf(5) to exist (created as part of the

Fix VOLUME_LABEL when BRANCH contains '-' and '.'

Insta-MFC ok: re (hrs)
Sponsored by: The FreeBSD Foundation

MFC r273653:
Fix a few issues with creating VOLUME_LABEL for the
installation ISOs:

- TYPE, BRANCH, and REVISION are only defined if
OSRELEASE is not defined, so in situations where
one might set OSRELEASE for an in-house ISO build,
VOLUME_LABEL would be empty.

- makefs(8) limits the volume label to 32 characters,
which for the powerpc64 case, OSRELEASE expands to
FreeBSD-11.0-CURRENT-powerpc-powerpc64. Even with
removing the prefixing 'FreeBSD-', the string is 30
characters long, leaving zero room for suffixing the
type of ISO media (BO for bootonly, CD for cdrom, and
DVD for dvdrom).

Resolve these by defining VOLUME_LABEL when defining
OSRELEASE if unset. If OSRELEASE is defined by the
builder, use the OSRELEASE from that definition as the
VOLUME_LABEL.

In addition, for cases where both TARGET and TARGET_ARCH
are used for the VOLUME_LABEL, use TARGET_ARCH if it
differs from TARGET.

There are probably a few sharp edges here yet, but these
problems are going to affect the powerpc/powerpc64 builds
for 10.1-RELEASE, so the immediate concern is fixing the
underlying problem at hand quickly, and less so about the
elegance of the fix.

r272234:
Initial commit to include virtual machine images as part
of the FreeBSD release builds.

This adds a make(1) environment variable requirement,
WITH_VMIMAGES, which triggers the virtual machine image
targets when not defined to an empty value.

Relevant user-driven variables include:

o VMFORMATS: The virtual machine image formats to create.
Valid formats are provided by running 'mkimg --formats'

o VMSIZE: The size of the resulting virtual machine
image. Typical compression is roughly 140Mb, regardless
of the target size (10GB, 15GB, 20GB, 40GB sizes have been
tested with the same result).

o VMBASE: The prefix of the virtual machine disk images.
The VMBASE make(1) environment variable is suffixed with
each format in VMFORMATS for each individual disk image, as
well as '.img' for the source UFS filesystem passed to
mkimg(1).

This also includes a new script, mk-vmimage.sh, based on how
the VM images for 10.0-RELEASE, 9.3-RELEASE, and 10.1-RELEASE
were created (mk-vmimage.sh in ^/user/gjb/thermite/).

With the order in which the stages need to occur, as well as
sanity-checking error cases, it makes much more sense to
execute a shell script called from make(1), using env(1) to
set specific parameters for the target image than it does to
do this in make(1) directly.

Add WITH_CLOUDWARE evaluation to RELEASE_RMAKEFLAGS.

Rewrite to consolidate VM image build scripts into one.

Fix duplicated mkimg(1) call in vm_create_disk().

Add primitive (untested) PowerPC/PowerPC64 VM image support.

Note: As it is currently written, the /boot/pmbr and
/boot/{gptboot,boot1.hfs} use the build host and not the

mount(8) and umount(8) devfs(5) as needed.

Change path for mk-vmimage.sh from ${TARGET}/ to scripts/ now that

Fix paths for the base image and output disk image files.

Set the boot partition type to 'apple-boot' for powerpc.

In vm_install_base(), copy the host resolv.conf into the build
chroot before attempting to do anything that requires working DNS
(i.e., pkg bootstrap).

In vm_extra_pre_umount(), remove the resolv.conf before the disk
image is unmounted from the backing md(4).

Silence errors when umounting the chroot's /dev, since it probably
doesn't exist when we're running this.

Unmount filesystems before attempting to destroy the md which
holds them.

Unmount filesystem and destroy md before we read the vnode from
disk and package it into a disk image. Otherwise we end up
packaging an unclean filesystem.

Merge duplicative vm-CLOUDTYPE targets before additional duplication
gets added by the impending arrival of ec2 and gcloud.

Add NOSWAP option which can be set by a vmimage.conf file to specify
that no swap space should be created in the image. This will be used
by EC2 builds, since FreeBSD/EC2 allocates swap space on "ephemeral"
disks which are physically attached to the Xen host node.

In vm_extra_install_packages(), only bootstrap pkg(8) if
VM_EXTRA_PACKAGES is empty.

In vm_extra_pre_umount(), cleanup downloaded packages if pkg(8) was
bootstrapped earlier.

In vm_extra_install_base(), do not install waagent in the openstack

Add vm_extra_pkg_rmcache() to call pkg-clean(8) to avoid duplicated
code.

Move resolv.conf(5) removal back to vm_extra_pre_umount() where it

The GCE image needs resolv.conf(5) to exist (created as part of the

Comment the line that configures ttys(5) to 'off', which makes it
impossible to test that the image boots.

Add a note explaining why the line is commented, and not (yet) removed

provider targets because CLOUDWARE was not yet set.

Move the WITH_VMIMAGES and WITH_CLOUDWARE targets to Makefile.vm.

Fix 'mini-memstick.img' prerequisite, which should be the 'bootonly'

Fix VOLUME_LABEL when BRANCH contains '-' and '.'

Insta-MFC ok: re (hrs)
Sponsored by: The FreeBSD Foundation

MFC r273653:
Fix a few issues with creating VOLUME_LABEL for the
installation ISOs:

- TYPE, BRANCH, and REVISION are only defined if
OSRELEASE is not defined, so in situations where
one might set OSRELEASE for an in-house ISO build,
VOLUME_LABEL would be empty.

- makefs(8) limits the volume label to 32 characters,
which for the powerpc64 case, OSRELEASE expands to
FreeBSD-11.0-CURRENT-powerpc-powerpc64. Even with
removing the prefixing 'FreeBSD-', the string is 30
characters long, leaving zero room for suffixing the
type of ISO media (BO for bootonly, CD for cdrom, and
DVD for dvdrom).

Resolve these by defining VOLUME_LABEL when defining
OSRELEASE if unset. If OSRELEASE is defined by the
builder, use the OSRELEASE from that definition as the
VOLUME_LABEL.

In addition, for cases where both TARGET and TARGET_ARCH
are used for the VOLUME_LABEL, use TARGET_ARCH if it
differs from TARGET.

There are probably a few sharp edges here yet, but these
problems are going to affect the powerpc/powerpc64 builds
for 10.1-RELEASE, so the immediate concern is fixing the
underlying problem at hand quickly, and less so about the
elegance of the fix.

r272234:
Initial commit to include virtual machine images as part
of the FreeBSD release builds.

This adds a make(1) environment variable requirement,
WITH_VMIMAGES, which triggers the virtual machine image
targets when not defined to an empty value.

Relevant user-driven variables include:

o VMFORMATS: The virtual machine image formats to create.
Valid formats are provided by running 'mkimg --formats'

o VMSIZE: The size of the resulting virtual machine
image. Typical compression is roughly 140Mb, regardless
of the target size (10GB, 15GB, 20GB, 40GB sizes have been
tested with the same result).

o VMBASE: The prefix of the virtual machine disk images.
The VMBASE make(1) environment variable is suffixed with
each format in VMFORMATS for each individual disk image, as
well as '.img' for the source UFS filesystem passed to
mkimg(1).

This also includes a new script, mk-vmimage.sh, based on how
the VM images for 10.0-RELEASE, 9.3-RELEASE, and 10.1-RELEASE
were created (mk-vmimage.sh in ^/user/gjb/thermite/).

With the order in which the stages need to occur, as well as
sanity-checking error cases, it makes much more sense to
execute a shell script called from make(1), using env(1) to
set specific parameters for the target image than it does to
do this in make(1) directly.

where compressing 20GB sparse images can take hours.

MFC r262499, r262505, r262507, r262509:

r262499:
release.sh:
- Add a VCSCMD variable that defaults to 'svn checkout',
and update places 'svn co' is used directly.
- After sourcing a configuration file, prefix SRCBRANCH,
PORTBRANCH, and DOCBRANCH with the SVNROOT.
- Properly capitalize 'FreeBSD.org' in the default SVNROOT.
- Update Copyright.

release.conf.sample:
- Add an example to use git instead of svn, by nullifying
SVNROOT, and setting SRCBRANCH, DOCBRANCH, and PORTBRANCH
to the URL fo a git repository.

release.7:
- Document VCSCMD.

r262505:
In release/Makefile, remove exclusion of CVS directories in the
src/ and ports/ distributions.

While I am thinking about it, exclude .git directories for src/
and ports/, as somewhat of a followup to r262499.

r262507:
Chase r262505, and remove CVS exclusion from picobsd builds.

r262509:
Rework how WORLD_FLAGS and KERNEL_FLAGS are set, to remove an
unnecessary expr(1) call.

MFC r260772:
Update the pkg-stage target to be more compatible with pkg-1.2:

- Add a release-dvd.conf pkg(8) configuration file to override
the default FreeBSD.conf configuration.
- Remove architecture-specific pkg-stage.conf files, consolidate,
and move their contents to scripts/pkg-stage.sh.
- Use 'pkg -vv' to determine the ABI, which is used as the
cache directory.

Prior to these changes, it would be possible for pkg-stage to fetch
conflicting binary packages from multiple repositories.

Tested against: head@r260522, stable/10@r260522

MFC r259729:
Bootstrap etcupdate(8) as part of the release build, similar
to what is done for mergemaster(8). This allows etcupdate(8)
to work out-of-box after the first upgrade of a system.

MFC r259426, r259427:
r259426:
Add a pkg(8) repository configuration file for cdrom-based package
installation.

As part of the 'pkg-stage' target, copy the configuration file
to the 'packages/repos/' directory on the DVD filesystem.

r259427:
Export 'REPOS_DIR' when the selected source medium for package
installation is cdrom. This enables bsdconfig(8) to make use
of the on-disc pkg(8) repository configuration, which fixes
package selection and installation from the dvd installer.

MFC r258770 (hrs):
Add NOPKG to disable pkg-stage.

MFC r259400:
Reduce disc1.iso size by 74MB by removing lib32 libraries, sendmail,
and atf.

Sponsored by: The FreeBSD Foundation

MFC r256430:
Reduce disc1.iso image size by installing the userland with
the WITHOUT_PROFILE=1 option set, trimming 56MB from the image.

This change was somehow lost during the 10.0-RELEASE cycle, and
is intended for MFC to releng/10.0.

MFC r257805, r257806, r257807, r257942:

r257805:
Add a 'mini-memstick.img' release target, which will use the
'bootonly.iso' components to create a smaller memory stick image.

This is useful for system recovery, where a full memstick.img image
is not necessarily needed (or wanted). In addition, it is possible
to do bootonly-style installation, where the base.txz, kernel.txz,
etc. are fetched from a remote source.

Provide backwards-compatible target (mini-memstick), to keep in sync
with the targets documented in release/Makefile.

r257806:
Remove extra target from 'memstick' that I forgot to remove before
previous commit.

r257807:
Update release(7) to include 'mini-memstick'.

r257942:
Fix a few style nits.

MFC r258786, r258796, r258797, r258847, r258853, r258949:

r258786:
Move OPTIONS_UNSET outside of the PBUILD_FLAGS variable, otherwise
the textproc/docproj port build fails.

r258796 (hrs):
- Prevent TARGET and TARGET_ARCH from being defined as empty when
TARGET="" and/or TARGET_ARCH="" is specified.
- Remove extra ().

r258797 (hrs):
Use standard CLEANFILES/CLEANDIRS and clean target in bsd.obj.mk.

r258847:
Provide reproducibility between builds by building pkg(8) from ports,
instead of using pkg-bootstrap.

This should resolve a problem that was discovered during 10.0-BETA4
freebsd-update(8) builds,

r258853:
Turn off the dvdrom target by default. dvd1.iso is now built by
specifying 'WITH_DVD=1' during 'make release'.

This caused some problems during the freebsd-update builds for
10.0-BETA4.

r258949:
Ensure WITH_DVD is not empty to prevent 'WITH_DVD= ' from evaluating
to true.

r258319, r258320:

r258305:
Use the IMAGES variable to determine which image files to remove
as part of 'make -C /usr/src/release clean'.

r258307:
Add a script and configuration files to fetch pre-built packages
from pkg.FreeBSD.org for inclusion on release medium (dvd1.iso).

r258308:
Unconditionally copy the build host /etc/resolv.conf into
the chroot directory, since hostname resolution may be
needed in the case of building a dvd image (with packages)
and also setting 'NOPORTS=1'.

r258309:
Set the PKG_CACHEDIR directory to 'dvd/' instead of 'release/'
in preparation of adding a 'dvd1.iso' target.

r258310:
Add the 'dvd1.iso' target. This mimics the 'release.iso' target,
with the additional step of fetching packages for inclusion on the
dvd image.

The 'pkg-stage' target is used to run 'scripts/pkg-stage.sh' if
the '${TARGET}/pkg-stage.conf' configuration file exists (currently
only amd64 and i386).

Allow dvd1.iso to be skipped if NODVD=1.

r258314:
Fix how ABI is evaluated so it matches more than a dot-zero
case.

r258317:
Document the 'dvdrom' target.

r258319:
Remove WITHOUT_PROFILE=1 for the dvd1.iso medium.

r258320:
Simplify PKG_ABI for pkg-stage.sh.
