* Persist urgent notifications * Create omarchy-snapshot * Create snapshot before pulling * Extract alternative bootloader configs * Add limine-snapper config * Fix check * Update login scripts * Make chroot friendly * Extract cmdline instead of using blkid due to error * Add restore command * Export $TERMINAL so we get clickable restore notifications * Remove sync -- causes errors...we have nothing to sync yet * Executable * Minor cleanup and compatibility for non-ISO * Give login its own section * Give no-arg guard and inline commands --------- Co-authored-by: David Heinemeier Hansson <david@hey.com>
