Boot entry Snapshots for Asahi Alarm

Installs and configures snapper + grub-btrfs on Arch Linux so BTRFS snapshots show up as boot entries in GRUB

Requirements

• Asahi Alarm
• BTRFS root filesystem
• GRUB bootloader
• sudo access

Install

git clone https://github.com/eightscrow/Asahi-Alarm-Snapshots.git && cd Asahi-Alarm-Snapshots && bash install.sh

What it does

1. Installs snapper, grub-btrfs, btrfs-assistant, snap-pac, inotify-tools
2. Creates snapper configs for / and /home (if /home is also BTRFS)
3. Applies retention policies — keeps hourly/daily/weekly/monthly snapshots, drops old ones automatically
4. Enables snapper-timeline.timer and snapper-cleanup.timer
5. Writes grub-btrfs config pointing at the correct GRUB directory
6. Creates a bootstrap snapshot if none exist, regenerates GRUB config
7. Enables grub-btrfsd so the snapshot submenu stays up to date without manual grub-mkconfig

After install, you'll see a snapshots submenu in GRUB on next boot.

Uninstall

bash uninstall.sh

Removes all packages, snapper configs, BTRFS subvolumes, and regenerates a clean GRUB config.
