I installed fai on an fresh debian system, and I forgot to add
repository to /etc/fai/apt/sources.list 
Thanks for pointing that out.

I needed LVM support and for that I had to have setup-storage
installed, otherwise setup_harddisks works just fine.


By the way, for fai-client 3.2.8 is it normal that installation fails if
a target hard drive contains LVM volume? I'm just wondering is this a
bug or a feature. The same disk layout configuration works if I erase a
couple of megabytes in the beginning of the disk.

I haven't looked closely on how to disable this behaviour and so far
It's been a minor annoyance,  

Here is an exempt of a log file:
