But what yo= u're doing isn't jail removal. Am existing jail is removed by running "jail -r", which will run the prestop and stop commands, actually remove the jail, then run poststop commands and then clean up mounts and IP address assignments. But note that you never r= an "jail -r". When a jail is created, it will (among other things) run the exec.start and= /or "command" commands. Those commands are not expected to all finish - genera= lly the command is something like "sh /etc/rc" which starts daemons which conti= nue to run. If all commands complete, and the jail isn't marked with the "pers= ist" parameter, the jail will naturally die on its own. That has nothing to do = with the jail(8) command, which is likely no longer running at the time, and whi= ch thus cannot running any of the shutdown commands. If you intend on running jails this way, I recommend unmounting the filesys= tems not in exec.poststop, but in exec.poststart which runs as the last step in = the creation process. --=20 You are receiving this mail because: You are the assignee for the bug.=
