[arch-general] Pacman fails to update?

[Martín Cigorraga]

Ok: thanks to the *excellent* Arch Wiki I had the idea too boot from the
Arch CD and take a look at /etc/pacman.d/mirrorlist.
To my surprise, or not, once I copy it to my Arch install it worked
allright.

I remember some days ago there was a discussion about how useful could be
using "Architecture = auto" instead "686" or "x86_64" in /etc/pacman.conf.
Since /etc/pacman.d/mirrorlist uses two variables passed by pacman which
first read in it's config file, may be a bug relating that's preventing
pacman from accesing repositories?

Also, weird enough, why in the world

[catalyst]
Server = http://catalyst.apocalypsus.net/repo/catalyst/x86_64

don't work!? Repo is online and perfectly accesible via web. Also it don't
use any variable in the url so what's going on here?
Getting more and more confused...
