Now that's it's possible to do all of this from the host system (by adding a process to a jail) there's no real need for an init type process anymore. As Michal mentioned, utilities like 'jailer' or 'kjailer' used to be necessary, but now a few simple utilities or scripts can manage a jail from the host system just fine. If these utilities were found in FreeBSD itself, it would round out the jail side of things nicely. Of course I'm partial to my own 'jailutils' but others that served the same purpose would work just as well. http://memberwebs.com/nielsen/freebsd/jails/jailutils/ The only thing I miss from this change is the inability to have per-jail consoles (which was possible with the 'jailer' package in 4.x), but that's another topic. Cheers, Nate
