I performed some updates on a server I manage which runs Gentoo today. There were a couple of hitches:
* Messages for package net-misc/neon-0.26.3: * There are new features in this version; please beware that * upstream considers the socks support experimental. If you * experience test failures (eg, bug 135863) then try rebuilding * glibc. * * Neon has a policy of breaking API across versions, this means * that any packages that link against neon will be broken after * updating. They will remain broken until they are ported to the * new API. You can downgrade neon to the previous version by doing...
The first one, neon, doesn’t seem to pose a problem, because I also updated subversion. The second isn’t a big deal, because I mostly access the server remote. I also haven’t had any problems with kbd though, I just think its odd if failed to emerge.
Also updated an even older gentoo machine, but had some problems with mysql:
[ERROR] Fatal error: mysql.user table is damaged or in unsupported 3.20 format.
The MySQL bit was actually quite a pain, but eventually it worked out. I pretty much had to rebuild the user db, but thankfully I only had a few users - root and an average user. I used:
mysqld_safe --skip-grant-tables --user=root &
as suggested by John Hunt, but I’m posting it above because his Wordpress is doing funky things to the characters making it hard to cut and paste into a terminal.
It sure is an odd experience managing both gentoo and debian machines, they are so different! Again one of these machines is really old - running a Gentoo install from several years back. The biggest problem with that upgrade is that the machine lost track of the HD ids. No longer able to find /dev/sdaX, I had to rebuild /etc/fstab with the likes of this:
I did run into some more minor issues too though:
* This package will overwrite one or more files that may belong to other * packages (see list below). Add "collision-protect" to FEATURES in * make.conf if you would like the merge to abort in cases like this. You * can use a command such as `portageq owners / ` to identify * the installed package that owns a file. If portageq reports that only * one package owns a file then do NOT file a bug report. A bug report is * only useful if it identifies at least two or more packages that are * known to install the same file(s). If a collision occurs and you can * not explain where the file came from then you should simply ignore the * collision since there is not enough information to determine if a real * problem exists. Please do NOT file a bug report at * http://bugs.gentoo.org unless you report exactly which two packages * install the same file(s). Once again, please do NOT file a bug report * unless you have completely understood the above message. * * Detected file collision(s): * * /usr/sbin/python-updater revdep-rebuild -X --library libexpat.so.0 * Any package that linked against the previous version * of gettext will have to be rebuilt. * Please 'emerge gentoolkit' and run: * revdep-rebuild --library libintl.so.7 * PLEASE PLEASE take note of this * Please make *sure* to run revdep-rebuild now * Certain things on your system may have linked against a * different version of com_err -- those things need to be * recompiled. Sorry for the inconvenience * You have had multiple versions of perl. It is recommended * that you run perl-cleaner now. perl-cleaner will * assist with this transition. This script is capable * of cleaning out old .ph files, rebuilding modules for * your new version of perl, as well as re-emerging * applications that compiled against your old libperl.so * * PLEASE DO NOT INTERRUPT THE RUNNING OF THIS SCRIPT. * Part of the rebuilding of applications compiled against * your old libperl involves temporarily unmerging * them - interruptions could leave you with unmerged * packages before they can be remerged. * * If you have run perl-cleaner and a package still gives * you trouble, and re-emerging it fails to correct * the problem, please check http://bugs.gentoo.org/ * for more information or to report a bug. * *
This one reminds me of the pam / shadow dual-block:
* * Your current setup is using the pam_stack module. * This module is deprecated and no longer supported, and since version * 0.99 is no longer installed, nor provided by any other package. * The package will be built (to allow binary package builds), but will * not be installed. * Please replace pam_stack usage with proper include directive usage, * following the PAM Upgrade guide at the following URL * http://www.gentoo.org/proj/en/base/pam/upgrade-0.99.xml
What I did:
auth include system-auth account include system-auth password include system-auth session include system-auth
And this is fine:
* * If you have just upgraded from an older version of python you * will need to run: * * /usr/sbin/python-updater * * This will automatically rebuild all the python dependent modules * to run with python-2.4. * * Your original Python is still installed and can be accessed via * /usr/bin/python2.x. *
But I didn’t have python-updater, it was blocked by my current version: 2.3.5. This forum thread helped me figure out what to do:
emerge --nodeps -v =dev-lang/python-2.4.4-r5
Only after that could I emerge -C =dev-land/python-2.3.5 and emerge python-updater.
Running Gentoo is definitely more stressful for me than running debian from time to time, but at the same point, I also find it a bit more satisfying as well, as I fell like I’m more in control and able to make more precise decisions. Its a trade off I guess.
Upgrading linux from 2.4 to 2.6
Told you one of my gentoo machines was old:
* You need a kernel of at least version 2.6.9 * for NPTL support! * * ERROR: sys-libs/glibc-2.6.1 failed. * Call stack: * ebuild.sh, line 1701: Called dyn_unpack * ebuild.sh, line 817: Called qa_call 'src_unpack' * ebuild.sh, line 44: Called src_unpack * glibc-2.6.1.ebuild, line 154: Called eblit-run 'src_unpack' * glibc-2.6.1.ebuild, line 150: Called eblit-glibc-src_unpack * src_unpack.eblit, line 117: Called toolchain-glibc_src_unpack * src_unpack.eblit, line 55: Called check_nptl_support * src_unpack.eblit, line 32: Called die * The specific snippet of code: * die "Kernel version too low!" * The die message: * Kernel version too low! * * If you need support, post the topmost build error, and the call stack if relevant. * A complete build log is located at '/var/tmp/portage/sys-libs/glibc-2.6.1/temp/build.log'. * * GNU info directory index is up-to-date.
Its running 2.4.28-grsec-2.1.0. I’m now updating to a non-grsec kernel : sys-kernel/gentoo-sources-2.6.22-r9. I’ve already switched to a standard profile, and am already using a standard gcc profile, so I hope it will be OK. I’m not sure exactly what kernel configuration I’ll need though, so I’m very thankful that I have this machine hooked up to a KVM over IP box so I can easily choose the original kernel. :-)
I’ll probably check to see if I have a config for my 2.4 kernel, but I’m doubtful that it would be friendly to the 2.6 menuconfig. Since I compiled the 2.4 kernel, I’ve learned a lot about how its done. Gentoo was the platform I really learned how to compile a kernel on my own, but I’ve since done it many many times on my various debian boxes, to enable /dev/crypto via ocf-linux as well as trying to enable better via C7 acpi cpufreq capabilities . Thankfully, they do have a Gentoo migration to 2.6 guide . Most of it doesn’t relate to me, but I was glad to read it anyway, at least to learn that make oldconfig won’t work.
AWESOME! It worked, I’m now running Gentoo’s 2.6.22 kernel. :-)
