Re: [condor-users] symlink vs perl script wrappers for Condor binaries

To follow up on my previous posting, the perl script also don't work
when invoked as

  /usr/local/bin/condor_status -pool condor.cs.wisc.edu
  /usr/local/bin/condor_userprio -pool condor.cs.wisc.edu

and reports "Can't read config file" in both cases.  If I run the actual
binaries /usr/local/condor/bin/condor_status and
/usr/local/condor/bin/condor_userprio, then I am able to see information
about the condor.cs.wisc.edu pool.

It looks like this perl script (put in /usr/local/bin) is a custom
modification of the file condor/etc/examples/condor.generic created by
the submit-only installation process.  Since the script isn't working in
several ways, can I safely move it aside and create symlinks to the
binaries, or is there a reason that the perl scripts are used to wrap
the binaries on the submit-only machine?
