I've just read some about 'fallback', and info in the grub manual about managing this without '--once'. Ie:
| default saved # This is important!!! | timeout 10 | | title the old kernel | root (hd0,0) | kernel /old_kernel | savedefault | | title the new kernel | root (hd0,0) | kernel /new_kernel | savedefault 0 # This is important!!! Then, using grub-set-default to set '1' and rebooting. As such, we absolutely need 'grub-set-default' in the images That name will unfortunately conflict with one provided by grub2, so probably will have to go with grub-set-default-legacy. -- grub-legacy-ec2 does not provide grub-reboot or grub-set-default https://bugs.launchpad.net/bugs/605910 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
