[Bug 637787] Re: grub2 approach can make system unusable if shit happens
Thanks for the quick reply. The "by name" approach will make sure a fixed entry is selected. If i understand the approach right it will not make sure that the "right" kernel is booted. On Ubuntu kernel updates new entries are automatically added. The "by name" approach will select the older kernel after update. For proper operation there would have to be some mechanism that allows to have "aliases" an select the alias for an entry. The update procedure would then have to give the grub entry the name "kernel x.y-latest" or something to have a stable alias that always points to the most current kernel. If the most current kernel does not work properly manual intervention would be possible by moving the alias just as the "by name" approach does. I don't know how to file a change request for two packages that are involved by this comment. Hopefully this comment will spawn some discussion and reaction to get the idea pushed into reality. -- grub2 approach can make system unusable if shit happens https://bugs.launchpad.net/bugs/637787 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 637787] Re: grub2 approach can make system unusable if shit happens
GRUB 2 has the option already; you just weren't using it. :-) Set GRUB_DEFAULT to the *name* of a menu entry rather than its number. I would rather not change the behaviour of numbers in GRUB_DEFAULT, because (a) it's very messy to have something automatically modifying a configuration file in /etc and (b) the current behaviour may well be useful. Names are the documented way to do this: `GRUB_DEFAULT' The default menu entry. This may be a number, in which case it identifies the Nth entry in the generated menu counted from zero, or the full name of a menu entry, or the special string `saved'. Using the full name may be useful if you want to set a menu entry as the default even though there may be a variable number of entries before it. If you set this to `saved', then the default menu entry will be that saved by `GRUB_SAVEDEFAULT', `grub-set-default', or `grub-reboot'. The default is `0'. ** Changed in: grub2 (Ubuntu) Status: New => Won't Fix -- grub2 approach can make system unusable if shit happens https://bugs.launchpad.net/bugs/637787 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
