[arch-general] [patch] AIF, discover repos on iso.

[Mark Pustjens]

Hi List,

The attached patch fixes a TODO in lib-pacman of aif.
Instead of hardcoding that `core' is always available locally and falling 
back to net for others, it now checks /src/ for repos.

It assumes repos are stored at /src/$repo/pkg/. All these repos are added 
as cache dirs.

While preparing pacman, a number of repo names are provided to be 
prepared.

All those repos which were requested are added as actual repo. If this 
repo is available locally, the url points to disk. Otherwise it falls back 
to the mirrorlist.

Please let me know what you think.

Greetings/Groetjes

Mark Pustjens

Currently there's five machines permanently networked here. They *all*
contain the serious core stuff. A couple of the machines are pensioned off
486s, with little other value now. Plus there's two Jaz drives in the
building and the portable also carries a fair amount of stuff. Plus every
Friday a man comes around and carves all the new stuff onto stone slabs and
buries them in the garden... I think I'm okay.
