Thanks for your response. Yes, I have mount.devfs; set. Otherwise I wouldn't have any device inside my jail. Verified - and like intended, right? Another notable discrepancy: The man page tells that devfs_rulset is "4" by default. But when I don't set devfs_rulset in jail.conf at all, inside the jail, 'sysctl security.jail.devfs_ruleset': 0 When set, like mentioned above, it returns the corresponding value, but it doesn't have any effect. How gets devfs_rulset handled? Does jail(8) do the whole job? I'd like to help finding the source, but have missed the whole new jail evolution.= =2E. Inside my jails, I don't have a fstab, outside I have them defined and enabled with "mount" - and noticed the non-reverted umounting. Thanks, -Harry --------------enig3E354507CAA76A8516AA8C46 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (FreeBSD) iEYEARECAAYFAlEh7FIACgkQLDqVQ9VXb8izDgCgyvgQON3OQ+hYduzQsvfB6RaD 6zYAoKefEHk6CGFzX0MueNShm4cpTCCP =KYYT -----END PGP SIGNATURE----- --------------enig3E354507CAA76A8516AA8C46--
