pjd 7e73da14eb Add security.jail.mount_allowed sysctl, which allows to mount and ... unmount jail-friendly file systems from within a jail. Precisely it grants PRIV_VFS_MOUNT, PRIV_VFS_UNMOUNT and PRIV_VFS_MOUNT_NONUSER privileges for a jailed super-user. It is turned off by default. A jail-friendly file system is a file system which driver registers itself with VFCF_JAIL flag via VFS_SET(9) API. The lsvfs(1) command can be used to see which file systems are jail-friendly ones. There currently no jail-friendly file systems, ZFS will be the first one. In the future we may consider marking file systems like nullfs as jail-friendly.
