Kristof Provost 9e9be081d8 devfs.rules: unhide pf in vnet jails
/dev/pf is usable in vnet jails, so don't hide the node there.

We shouldn't expose /dev/pf in regular jails, as that gives them control over
the host (or parent vnet jail) firewall.

# The following are some default rules for devfs(5) mounts.
# The format is very simple. Empty lines and lines beginning
# with a hash '#' are ignored. If the hash mark occurs anywhere
# other than the beginning of a line, it and any subsequent
# characters will be ignored. A line in between brackets '[]'
# denotes the beginning of a ruleset. In the brackets should
# be a name for the rule and its ruleset number. Any other lines
# will be considered to be the 'action' part of a rule
# passed to the devfs(8) command. These will be passed
# "as-is" to the devfs(8) command with the exception that
# any references to other rulesets will be expanded first. These
# references must include a dollar sign '$' in front of the
# name to be expanded properly.

# Very basic and secure ruleset: Hide everything.
# Used as a basis for other rules.
