 # ArchRepo
-## Version 2
+## Version 1
-
-### Past versions
-* [Version 1](https://gitea.kto.black/alex/archrepo/src/branch/version1) is the previous version, running state-fully in
-a dedicated VM, which uses NFS to mount the repository (and thus works only on a local network)
-  * [Version 1.1](https://gitea.kto.black/alex/archrepo/src/branch/version1.1), currently used, is an adapted version 1
-  with support for a remote repository (via SCP)
 
 ### Introduction
-Version 2 targets an all-new architecture:
+In a nutshell:
-* written in Python
+* this script is run punctually, on a dedicated Arch VM;
-* running in a container
+* Process:
-  * potentially a stateless and ephemeral container
+  * it takes all packages in the repository;
+  * checks online if a new version is available
+  * if so build it and then add it to the repository

-# KTO ArchRepo update script
-# version 2.0
-
-# The purpose of this script is to automate the maintenance of a custom pacman (Arch Linux) repository, whose goal is to
-# provide already built packages of AUR software.
-
-# This version 2 aims at 2 major evolutions:
-# * manage dependencies (hence Python and object-oriented programming);
-# * run this script in a stateless Arch container, rather than a full VM as in version 1.
-# Additionaly, we may like to manage working directory in a better way (check available storage space, and existing
-# directories).
-
-# This script should NOT be run as root. Or should it?
-# * We are in a stateless container, but I don't think we can run makepkg as root...
