I'm trying to set up LVM with FAI 3.4.7 on Debian 6. The various
partitions are created, and things install fine, but on reboot all the
volume groups except the the one that has the root file system ("/") are
'inactive'.

Please try:
-   disk_config cciss/c0d0 disklabel:msdos fstabkey:uuid
+   disk_config disk1 disklabel:msdos fstabkey:uuid
....
-   vg              vgsys   cciss/c0d0p2
+   vg              vgsys   disk1
