So it should be in /etc where they can do so. So they should mail here if they find substantial functionality missing. Until then they continue to not enable xencommons and run their own startup script. > I don't think this script wants to contain an option parser! How should it handle exec vs. no-exec?

Perhaps the forking has some overhead and it returns earlier than it can process requests. If thats the reason why the loop exists in the sysv runlevel script then that loop should be used only without --no-fork.
