> we are considering whether a jail should have its own init... Just FYI: The AIX version of jails each had their own init process. I wasnt = directly working on that project/team, so I dont know all the details. = The only thing I remember was a few bugs my co-workers mentioned: first = there were several places that assumed init was pid 1, and they all = needed changing. Second was I think some weird issues managing when the = jails init was supposed to actually quit. Last, when AIX wanted to send = a signal to a processs parent like SIGCHILD, AIX needed to be careful = which init to send it to for unparented processes, otherwise an init = would get a signal for a process id it couldnt actually see.
