Re: replace our mount code with calls to /bin/mount

[Chris Lumens <clumens redhat com>]

That was an unhelpful blank error message.  Here's what it should have
said:

The attached patches remove all our own mount code from isys and replace
it with calls to /bin/mount and /bin/umount.  To keep the changes as
contained as possible, I've just changed doPwMount.  The callers didn't
require very much modification.

This has only been tested on NFS installs so far, as I found an
unrelated segfault in the HTTP code that I haven't gotten to fixing, and
then my computer exploded.  But does everyone like the direction these
patches are going in?
