ALT Linux Bugzilla – #53849

Или если вычисляется, что версия backup==booted, то также лучше оставлять предпоследнее, не загруженное.

(Backup kernel is the same as booted kernel (uptime 14 days).)

Дело в том что "предпоследние" ядра -- не резервные. Резервное ядро - которое было успешно загружено и up в течении суток и более.

Виталий, выскажу свои мысли.

По первому примеру:

># last -a reboot
>reboot   system boot  Tue Apr  1 13:29 - 08:19 (14+18:49)   6.1.131-un-def-alt1
>reboot   system boot  Tue Apr  1 13:24 - 13:29  (00:04)     6.1.121-un-def-alt1
>reboot   system boot  Tue Feb  4 12:12 - 13:22 (56+01:10)   6.1.121-un-def-alt1
>reboot   system boot  Mon Jan 27 14:25 - 12:11 (7+21:46)    6.1.121-un-def-alt1
>reboot   system boot  Tue Jan 21 13:39 - 14:25 (6+00:46)    6.1.121-un-def-alt1

Но в good_kernel попадает текущее ядро, так как у него больше 1 дня аптайм:
># good_kernel=$(LC_ALL=C last -a reboot | awk '$ 10 ~ /+/ {print $10,$11; exit }')
># echo $good_kernel
>(>14+18:51) 6.1.131-un-def-alt1

В таком варианте лучше бы искать другое ядро, кроме текущего, у которого аптайм более суток.


По второму примеру в логах вообще только одно ядро, так как на сервере включен расширенный аудит, и логи забиваются этим аудитом (вычищая записи с reboot), хотя по аптайму ядер там примерно также как с предыдущим примером:
># last -a reboot
>reboot   system boot  Tue Apr 15 09:03 - 08:19  (23:16)     6.1.131-un-def-alt1

И тогда remove-old-kernels не предлагает вообще ни одного запасного ядра.

Понятно, что лучший вариант, оставлять ядро, у которого аптайм >1 дня, но в случае, если таких не нашлось, как запасной вариант оставлять хотя бы предпоследнее.

Лучше иметь хоть одно запасное ядро, чем вообще не иметь никаких.

Не думаю, что исправление eepm может как-то повлиять на работу update-kernel.

update-kernel-1.25-alt1 -> sisyphus:

Tue Oct 20 2026 Vitaly Lipatov <lav@altlinux.ru> 1.25-alt1
- Fix update-kernel to select the next numeric flavour by kernel version,
  not by uname with the flavour name (closes: #51945).
- Call ldconfig by full path in update-kernel (closes: #40428).
- Install kernel headers of the selected build in update-kernel when they
  are in RPM::Allow-Duplicated (closes: #36936).
- Take release files into account in the update-kernel APT database age
  check, apt-get update does not rewrite unchanged pkglists.
- Keep the previous kernel with uptime of more than a day as the backup in
  remove-old-kernels when the booted kernel has it too (closes: #53849).
- Allow to list kernels to remove on the remove-old-kernels command line
  (closes: #55852).
