PBS via rpm and bash variables

[Peter Jay Salzman]

dear all,

i installed pbs on our front end and am reading the docs right now.

i need to set a bash variable PBS_HOME.  however, since i installed an rpm
instead of compiling pbs from source, there might be a directory already
picked out to be PBS_HOME.

if so, i can't find it in the docs.   looking at the output of
	rpm -ql pbs-2.2-5RH6
it looks as if that directory might be /usr/spool/pbs.

is that right?  or does it not matter what i call PBS_HOME?  it's hard to
tell if the rpm binaries have been compiled with a hardcoded PBS_HOME or
not.

thanks!
