pacman-offline
==============

**Run offline system update with pacman.**

The offline system update with pacman is achieved by integrating into
[offline updates in systemd](https://www.freedesktop.org/software/systemd/man/systemd.offline-updates.html).
In fact only two scripts and a number of systemd unit files are used to
glue `systemd` and `pacman`.

Requirements
------------

There are the runtime dependencies:

* [pacman](https://archlinux.org/pacman/)
* [systemd](https://www.github.com/systemd/systemd)

Optional basic support for
[plymouth](https://www.freedesktop.org/wiki/Software/Plymouth/) is
integrated.

Usage
-----

A single command `pacman-offline` is used to prepare the offline update.
It accepts some arguments:

* *-c*: clean before download
* *-f*: force if other system-update is pending
* *-h*: show help
* *-p*: reboot, install and poweroff immediately
* *-r*: reboot and install immediately
* *-t*: start timer for nightly reboot
* *-y*: update sync databases

### Timer for preparation

You can enable a timer to prepare the offline update automatically.

    systemctl enable pacman-offline-prepare.timer

This will trigger several minutes after boot, then ever day. The databases
are synced, then packages are downloaded. The updates are installed when
ever the system reboots.

### Timer for nightly reboot

You can enable a timer for nightly reboot:

    systemctl enable pacman-offline-reboot.timer

This will trigger at night, if updates are pending and prepared.

Configuration
-------------

A sinppet for inclusion in `/etc/pacman.conf` is shipped. To make use of
it add this line:

    Include = /etc/pacman.d/offline.conf

It will cause `pacman` to ignore linux packages and prevent breaking module
loading. These packages are not ignored on offline update.

Modify `/etc/pacman.d/offline.conf` to your needs by changing or adding
packages.
