%description
grub-btrfs improves the grub bootloader by adding a btrfs snapshots sub-menu, allowing the user to boot into snapshots.
grub-btrfs supports manual snapshots as well as snapper, timeshift, and yabsnap created snapshots.
- Automatically lists snapshots existing on the btrfs root partition.
- Automatically detect if /boot is in a separate partition.
- Automatically detect kernel, initramfs and Intel/AMD microcode in /boot directory within snapshots.
- Automatically create corresponding menu entries in grub.cfg
- Automatically detect the type/tags/triggers and descriptions/comments of Snapper/Timeshift/Yabsnap snapshots.
- Automatically generate grub.cfg if you use the provided Systemd/ OpenRC service.
