This simple bash script allows you to emulate Gnome's package manager behavior which downloads packages for safe offline installation with a reboot.

The script can download all available system updates (and optionally create a btrfs snapshot for you first). A notification will show once updates are available for installation, at which point you can simply reboot to have them installed for you.

The script can be easily integrated with chron or systemd to ensure periodic updates.

Note that BTRFS snapshot support requires snapper to be installed.

Syntax: pkcon [-b]
options:
-b, --btrfs     Create btrfs snapshot for the root subvolume. Optionally supply the desired subvolume.
                'root' assumed otherwise. Requires snapper
-h, --help      Display this help and exit.
