[Lerftest-ctrls] set_profile no longer works

We did not expect this environment to deviate from a regular linux setup (e.g., /home). So either we need to copy /s/home/screen/* over to /home, or create a symlink to /s/home/screen in /home for iocConsole to work. Any other workaround would require changing the iocConsole application itself.

So calling /s/home/screen/bin/screen or putting /s/home/screen/bin upstream in the path won’t solve that?

The environment is isolated.  But JLAB staff have to be able to login use it, requiring a /home for all of them (and it’s a lot between operators, SRF staff, etc).  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.
