[Lerftest-ctrls] set_profile no longer works

Patrick,

Mistyped…  Looks like it might come from $SCREENBIN=/home/screen/bin, but my understanding could be way off.  

If it’s really not pulled from the env, I can look to mirror the screen account on the jlab-side to give us a workaround.

Only a few of you actually need/want /home as spec’d out for this environment.  So for this case you guys become the exception, not the rule.  For those softegr/laci/etc defining it in /etc/passwd is all that’s needed.  No one spoke up about screen, nor is it an actual user.

The /home/screen directory has the sticky bit set so that individual users can attach/detach multiple screen sessions to an IOC. Without this set up properly, iocConsole won't work and our controls developers won't be able to work on their IOC applications.
