Yes. I run FreeBSD on a second machine that I keep as a small server, and
its disks are UFS2. I mount those from my Linux box with the in-tree ufs
driver to read data off them, which on Linux is read-only for UFS2. So the
driver is not theoretical for me, it is how I reach my own data.

More generally that is what the driver is for: reading FreeBSD, NetBSD,
OpenBSD and Solaris disks from Linux. Anyone dual booting a BSD, migrating
data off one, or doing recovery or forensics on a BSD or Solaris volume
ends up here. It is a small user base but not an empty one, and it is the
only in-tree way to do it.

That is also why the mount path bugs bother me. The images I feed it are
real BSD volumes, sometimes left unclean after a crash, so an unusual but
legitimate on-disk layout should not panic the kernel. The fixes I have
been sending are all in that parse and mount path.

Thanks,
