I don't know if this related, but I had to mount a NetBSD root
filesystem on a Linux (Debian). The page:

http://wiki.netbsd.org/tutorials/how_to_mount_ffs_partition_under_linux/

stated to use:

mount -t ufs -o ro,ufstype=44bsd 

for NetBSD. But the filesystem was not recognized. I had to use:

mount -t ufs -o ro,ufstype=ufs2

(the same as for FreeBSD).

The page was "Last edited 3 years and 4 months ago". At least it gives
perhaps a reference point in time to search what has been changed.

FWIW,
