[Mageia-dev] Cauldron Install borked

[Frank Griffin]

Doing a fresh install, after partitioning but before package selection 
(last popup shows "looking for installed packages"), you get an error 
panel saying:

An error occurred
rm of /mnt/var/cache/urpmi/mirrors.cache failed: No such file or directory
Clicking OK sends you back to disk partitioning again.

Why should a failed rm halt the install ?
