[Lerftest-ctrls] set_profile no longer works

Sounds good Patrick.  I think we should follow-up to try to understand what the issue was.  We can turn puppet off on a host and do any testing you need to.  

To sum up the current workaround:

- Changed /home to point to /u/home/links, a directory containing CUE home symlinks.
- On CUE fileserver, added screen -> /s/home/screen, which will only resolve on our LCLS hosts.
