https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=222951 Bug ID: 222951 Summary: Re-starting a jail with mount.devfs mounts devfs multiple times Product: Base System Version: 11.1-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: freebsd-bugs@FreeBSD.org Reporter: vlad-fbsd@acheronmedia.com Starting a jail that's configured with 'mount.devfs' with `jail -c` does not check if devfs is already mounted and mounts it again. The problem seems to be when the (nopersist) jail is stopped by itself because all the processes in it have exited, so it wasn't explicitly `jail -r`. When that happens, devfs is not unmounted. So next time the jail is started, devfs is mounted again, resulting with multiple mounts of devfs into $JAIL_ROOT/dev: > % mount | grep /zroot/jails/test/dev > devfs on /zroot/jails/test/dev (devfs, local, multilabel) > devfs on /zroot/jails/test/dev (devfs, local, multilabel) > devfs on /zroot/jails/test/dev (devfs, local, multilabel) > devfs on /zroot/jails/test/dev (devfs, local, multilabel) If the jail is explicitly stopped with `jail -r`, devfs is unmounted. -- You are receiving this mail because: You are the assignee for the bug.
