NFS filesystem check on Hobbit client

[Matthew Epp <matthew.epp (at) us.army.mil>]

I've written a slight mod for the filesystem check for the 
hobbitclient-sunos.sh client file. I didn't want to have an external 
script doing the NFS check, nor do I want the client hanging if the 
filesystem becomes unavailable. The difficulty is always those timeouts. 
The only command I've found (without installing something else) is the 
showmount command. It times out after 15 seconds, so that shouldn't tie 
up the Hobbit client for too long.

Can someome with a test server, they can control the shares on, run some 
tests with this code and make sure it works ok in case of a real 
failure? Note: the <tab> indicators are to be replaced by real tab 
characters since \t doesn't work with egrep for some reason.

set $FSTYPES
/bin/df -F $1 -k | grep -v " /var/run"

while test "$1" != ""; do
  /bin/df -F $1 -k | grep -v " /var/run" | tail +2
