Sarge branch build dies with free blocks count == 0

[Daniel Dickinson <d-f-d@d-f-d.net>]

Trying to make all_build on the sarge branch, using testing in 
source.list.udeb.local fails with the following error:

I'm trying again with unstable, but won't see the results until I get 
back from Christmas.

The superblock could not be read or does not describe a correct ext2
filesystem.  If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>
