The default being not all= owed. I'm worried about making allow.read_msgbuf default to not allowed, for the reason that current behavior wouldn't be preserved. A jail without a particular option should generally behave the same as an older jail when the option didn't exist. There may be exceptions to this, but I don't see it h= ere. --=20 You are receiving this mail because: You are the assignee for the bug.=
