Arch Wiki Limine mentions:
- Supports booting into selected Snapper snapshot. Offers two different methods for restoring a system snapshot: rsync or btrfs.
- After restoring a snapshot, a “backup” entry is added to the Limine bootloader, providing an easy way to revert to the “backup” if needed.
- Automatically repairs corrupted bootable files from old snapshots on the ESP when a new snapshot with the same bootable files is created.
- Automatically logs error messages about potential hardware issues if two hashes of the same bootable file do not match on the ESP.
- Testing read-only snapshots: Use overlayfs to test any installed packages on an immutable-like system without modifying the original data. Note that this does not mean testing the boot partition or a separate home subvolume/partition.
I wanna encrypt my BTRFS system, but not the FAT32 boot part. Only the Linux kernels are on FAT32 anyway, and I don’t care about encrypting those — they’re public stuff, not private files. I just let limine-entry-tool hash them to make sure they’re clean for booting, that’s totally fine for me.
I don’t like putting kernels on the Linux filesystem for GRUB — it just makes booting slower and causes random issues.
