[arch-releng] [RFC] [PATCH] [configs/releng] Rework make_customize_root_image()
by Gerardo Exequiel Pozzi 28 Oct '12

28 Oct '12

Using a separate shell script to customize live-enviroment, makes much more readable code. Move all thing except: * Need network access (name resolving). * Need access to some file outside chroot.

Building i686 under x86_64 not so easy 'linux32' was not working for me. So am building packages on a virtual 32 bit machine [not ideal!]. As I only have a couple of packages I need to build it is not real problem at the moment. Managed to edit build script to only build both [all] 32 & 64 nice! saves me a lot of time.

[arch-releng] Building both 32&64 with custom packages
by Mr Green 27 Oct '12

27 Oct '12

I have got my build script working building both i686 and x86_64 without problem. Have custompkg repo set in pacman.conf for dmenu-xft [from AUR]. Not sure if pacman will work if I set both custom repos... only other way I can think of is sed pacman.conf [for i686 or x86_64]. Never tried using a custom repo that had both 32&64 packages anyone got any better ideas?
