This implies the -q option -q Suppress the message printed whenever a jail is created, modif= ied or removed. Only error messages will be printed. however, this does not reflect how jail behaves. In addition to error messa= ges, it also prints all output from, for example, 'exec.start'. This can lead to the output of jail being rather odd, and hard/impossible? = to parse and it seems in conflict with 'Only error messages will be printed.' = as the output from 'exec.start' is not an error. That all said I can see why this happens, I suspect the output of exec.star= t is not considered to be output from the jail command. It is however pointed to= the same FD (stdout) so I think for all intents and purposes, as anyone calling jail the output comes from jails. This bug can simply be reproduced by creating a new jail using the -i option and adding exec.start=3D"echo hello". --=20 You are receiving this mail because: You are the assignee for the bug.=
