Re: Actually 1.3.4; "mount" closes bash window after tape drive ops

["Larry Hall (RFK Partners, Inc)" <lhall at rfk dot com>]

Since this is the first I've noted of this problem being reported to the
list (did I miss some much earlier report(s)), I would say that one 
shouldn't expect that it would be addressed specifically in any recent 
release.  Unless the problem turns out to be more generic, it's probably 
going to remain a problem.  Perhaps you want to try running mount under 
strace and see if the log that results indicates anything useful.

Just a thought.
