====== ACM Arch Linux Repo ======

====== What is is? ======

The ACM custom repo is a local package repository for internal ACM packages. One example being the [[linux:lxdm_login_theming_setup|LXDM themes]] used by the ACM/LUG workstations.
It currently only supports packages with arch type "any".

The PKGBUILDs and files are stored in a git repo on the ACM system.

====== Client Side ======

===== Arch Linux =====

Add the mirror to the workstations pacman config

<file|pacman.conf>
[uicacm]
SigLevel = Optional TrustAll
Server = http://mozart.acm.cs/acm-packages/archlinux/
</file>

then sync the repo DB

<code>
pacman -Sy
</code>
====== Server Side ======

Currently the repo is hosted on mozart.acm.cs 

The files are located under the standard archlinux http root /srv/http

Clone the repo and build the packages with makepkg. All the current version symlinks should be in place, but double check if you have updated a version.
