This is a couple of scripts that enable the use of pacman to perform system updates using systemd's system update mechanism. This means that in order to use these scripts, you must be using a Linux-based distribution using pacman as a package manager and systemd running as init (PID 1).
Typical usage looks like this:
- Synchronize pacman's database:
sudo pacman -Sy - Optionally, download the updated packages in advance:
sudo pacman -Suw - Schedule a system update:
sudo schedule-system-update - Reboot
Install the package from the AUR.
The first script is schedule-system-update.
Run this script as root (e.g. with sudo)
to schedule a system update for the next reboot.
All this does is create the file /system-update.
On your next reboot,
systemd will see this file
and perform the system update
instead of performing a normal system boot.
The second script is perform-system-update.
This is referenced by system-update-pacman.service,
a systemd service unit that will be started to perform the system update.
You do not run this script manually.
It removes /system-update
(otherwise, systemd will keep launching system updates on each boot),
then runs pacman -Su --no-confirm to update the system.
Note that this does not pass the -y flag to sync the database.
You should sync the database and review the updates
before performing a system update.
