The Hurd's ufs can grok a BSD-format filesystem but will write translators
and other Hurd magic onto it, and then BSD's fsck won't know about that and
will screw it up. Note that we really haven't tested this much in a long
time, so if the BSD ffs code has changed format details then the Hurd ufs
may not be able to understand them. Try it and see.

Yes, it is mandatory on an ext2fs filesystem to use `-o hurd'. The silver
lining of this cloud is that the standard e2fsck (on Linux or whereever)
will see this and know about the translator blocks and not squash them.

The e2fsprogs package is reasonably portable and easy to compile on a
random system.
