Martin Matuska bf3db8aa65 To improve control over the use of mount(8) inside a jail(8), introduce ... a new jail parameter node with the following parameters: allow.mount.devfs: allow mounting the devfs filesystem inside a jail allow.mount.nullfs: allow mounting the nullfs filesystem inside a jail Both parameters are disabled by default (equals the behavior before devfs and nullfs in jails). Administrators have to explicitly allow mounting devfs and nullfs for each jail. The value "-1" of the devfs_ruleset parameter is removed in favor of the new allow setting.
