Must stop replying to these things before I've had enough coffee.=20
fstat(1) is of course installed as /usr/bin/fstat so unmounting /usr
will seriously cramp its style. As you say -- there are no shlib
dependencies on stuff under /usr so just slap a copy somewhere on
the root partition and away you go.
Cheers,
Matthew, who avoids having to think about any of this stuff=20
by the simple expedient of not having a separate /usr
partition.
