We mounted a floppy that contained a ufs filesystem created
on a DEC Alpha running Digital Unix 4.0D on both A Red Hat
5.2 and 5.1 machine. and Get the following:

[root@braindead /root]# mount -t ufs /dev/fd0 /mnt/m
ufs_read_super: fs_nindir 2048 != 3
ufs_read_super: fucking Sun blows me
ufs_read_super: fs last mounted on "/mnt"
ufs_read_super: fs needs fsck
ufs_read_inode: file too big ino 2 dev 2/0, faking size
ufs_read_super: inopb 64

We figured you might like to know that some (not us) might
find the "ufs_read_super: fucking Sun blows me" comment
might be offensive. Almost forgot... the floppy does mount
but we can't read any thing on it. Haven't tried a Sun
created UFS floppy but I suspect you'll see the same.
