[Lerftest-ctrls] set_profile no longer works

Hi Wesley,

It looks like setting SCREENBIN and SCREENDIR don't seem to resolve the issue with iocConsole, as the /s/home/screen/bin/screen utility fails to write to /s/home/screen/sock due to some permissions issues. Can you try copying /s/home/screen/* over to /home?

My mistake, I was under the impression that iocConsole was hardcoded in some fashion. Let me try changing that env, although I'm not entirely sure if any other scripts or utilities use it.

iocConsole picks it from $SCREEN, no change to the code required (exactly why you don’t hardcode stuff like that).  Why is changing that env variable not an acceptable fix?

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.
