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 trust DeepSeek Open Source if it allows me to copy and review it. I don't trust ~~Open~~AI like ChatGPT.
