UPDATING revision 62050
1Updating Information for FreeBSD current users 2 3This file is maintained by imp@village.org. Please send new entries 4directly to him. See end of file for further details. For commonly 5done items, please see the end of the file. Search for 'COMMON 6ITEMS:' 7 820000622: 9 The license on the softupdates is now a standard 2 clause 10 BSD license. You may need to remove your symbolic links 11 that used to be required when updating. 12 1320000621: 14 Scott Flatman <sf@aracnet.com> sent in a decent writeup on 15 the config file update procedure. 16 http://people.freebsd.org/~imp/config-upd.html 17 1820000620: 19 Binutils 2.10 have hit the tree, or will shortly. As soon 20 as they do, the problem noted in 20000522 will be resolved and 21 that workaround will no longer be required. 22 2320000615: 24 phk removed the compatibility creation of wd devices in the 25 ad driver. If you haven't done so already, you must update 26 your fstab, etc to use the ad devices instead of the wd 27 devices. 28 29 In addition, you'll need to update your boot blocks to a 30 more modern version, if you haven't already done so. Modern 31 here means 4.0 release or newer (although older releases 32 may work). 33 3420000612: 35 Peter took an axe to config(8). Besure that you read his mail 36 on the topic before even thinking about updating. You will 37 need to create a /boot/devices.hints or add a hints directive 38 to your config file to compile them in statically. The format 39 of the config file has changed as well. Please see LINT, 40 GENERIC or NEWCARD for examples of the new format. 41 42 More details to follow. A better howto would be warmly 43 accepted by the author of UPDATING. 44 4520000522: 46 A new set of binutils went into the tree today. Anybody 47 building a kernel after this point is advised that they need 48 to rebuild their binutils (or better yet do a 49 buildworld/installworld) before building a new kernel. 50 51 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf 52 or MALLOC_OPTIONS env var) J will cause ld to dump core. It 53 is recommended that you don't set this option until the problem 54 is resolved. 55 5620000513: 57 The ethernet drivers were all updated to clean up the BPF handling. 58 5920000510: 60 The problems with boot blocks on the alphas have been corrected. 61 This will require some care in updating alphas. A new libstand 62 is requires for the boot blocks to build properly. 63 6420000503: 65 Recompile all kld modules. Proper version dependency info 66 is now available. 67 6820000502: 69 Modules have been disconnected from the buildworld tree and 70 connected to the kernel building instead. 71 722000427: 73 You may need to build gperf 74 cd /usr/src/gnu/usr.bin/gperf && make depend all install 75 when upgrading from 4.0 -> current. The build system now uses 76 an option only in -current. 77 7820000417: 79 The method that we brand ELF binaries has changed to be more 80 acceptible to the binutils maintainers. You will need to 81 rebrand your ELF binaries that aren't native. One problem 82 binary is the Linux ldconfig. After your make world, but 83 before you reboot, you'll neeed to issue: 84 brandelf -t Linux /compat/linux/sbin/ldconfig 85 if you have Linux compatibility enabled on your machine. 86 8720000320: 88 If you have really bad/marginal IDE drives, you may find they 89 don't work well. Use pio mode instead. The easiest way to 90 cope if you have a problem combination is to add: 91 /sbin/sysctl -w hw.atamodes=pio,pio,pio,pio 92 to the start of /etc/rc.conf. 93 9420000319: 95 The ISA and PCI compatability shims have been connected to the 96 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old 97 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must 98 include the appropriate option in your kernel config. Drivers 99 using the shims should be updated or they won't ship with 100 5.0-RELEASE, targeted for 2001. 101 10220000318: 103 We've entered the tradtional post release dumping party. 104 Large kernel changes are being committed and are in the 105 works. It is important to keep the systems' klds and kernel 106 in sync as kernel interfaces and structures are changing. 107 Before reporting kernel panics, make sure that all modules 108 that you are loading are up to date. 109 11020000315: 111 If you are upgrading from an older version of FreeBSD, you 112 need to update your boot blocks as well. 'disklabel -B ad0' 113 will do the trick. This isn't critical until you remove your 114 wd device entries in /dev, at which point your system will not 115 boot. 116 11720000315: 118 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how 119 to upgrade to 4.0 from 3.x. 120 121COMMON ITEMS: 122 123 To build a kernel 124 ----------------- 125 Update config, genassym and go: 126 config YOUR_KERNEL_HERE [1] 127 cd ../../compile/YOUR_KERNEL_HERE 128 make depend && make 129 make install 130 [1] If upgrading, add -r won't hurt and sometimes helps. 131 132 To rebuild everything 133 --------------------- 134 make world 135 136 To upgrade from 4.0-stable to current 137 ------------------------------------- 138 make buildworld 139 make buildkernel KERNEL=YOUR_KERNEL_HERE 140 make installkernel KERNEL=YOUR_KERNEL_HERE 141 make installworld 142 <reboot> 143 144 Make sure that you've read the UPDATING file to understand 145 the tweaks to various things you need. At this point in the 146 life cycloe of current, things change often and you are on 147 your own to cope. 148 149FORMAT: 150 151This file contains a list, in reverse chronologocal order, of major 152breakages in tracking -current. Not all things will be listed here, 153and it only starts on March 15, 2000. Updating files can found in 154previous releases if your system is older than this. 155 156Please filter your entries through Warner Losh (imp@village.org) so 157that the style, formatting, etc of this file can be maintained. 158 159$FreeBSD: head/UPDATING 62050 2000-06-25 08:26:38Z imp $ 160
