At LIGO Livingston, we have also used the ‘tmux’ system for doing the same thing
At LIGO Hanford, I believe they are using procServ for some

Yes, I know, yet more ways to do it

This is accomplished on headless systems by exploiting the 'stuff' command of the screen applicaton to stuff commandlines into the screen session to launch the IOC application(s). Logging is done by screen, and log rotation using conventional logrotate tools.
