Comment 1 Richard W.M. Jones 2009-06-22 15:08:01 UTC

Reportedly this happens with the following image:

Comment 2 Richard W.M. Jones 2009-06-22 15:39:35 UTC

Looks like the interesting error is:

MAKEDEV: no such group: floppy

I looked at the source for MAKEDEV[1] and if it encounters
this error, it will quit early without creating any of the
rest of the devices.

I confirmed with Marek that the floppy group is missing from
/etc/group, and also that only devices up to the point of
making the floppy devices were created.

Long fixed, since we now use udev to create the devices.
