Running into that errno in my program I was puzzled because uid was 0 - so = that could not have been the problem. After help from other people I found out that there might be other, undocumented, reasons for getting that errno. Specifically, the issue was that the process was holding a directory FD open while trying to attach, which is prohibited. A sentence describing this behavior should be added to "[EPERM]" in jail_attach(2) "ERRORS" section. --=20 You are receiving this mail because: You are the assignee for the bug.=
