This has been bothering me for a while; A single execute service
operates like a traditional Emulab startup command, with output going to
/proj/pid/exp/eid/logs, which is a pain in the ass cause I don't know
the name of the file and there 1000s of file in the directory.

But when there are multiple execute services, we wrap them in a script
and redirect the output to easy an easy to find spot; /var/tmp. Much
nicer.

Now we always wrap them up in a script so the output files go to
/var/tmp. And drop a note in the original file that says where to go
look.

The script is written to /proj/pid/exp/eid, but thinking to the future
when there are no NFS mounts at all, we now bundle that script into a
little tarball and append that to the install services. Tarballs already
handle a no-NFS world, asking the web server for the file. QED
