1#
2# The following are some default rules for devfs(5) mounts.
3# The format is very simple. Empty lines and lines beginning
4# with a hash '#' are ignored. If the hash mark occurs anywhere
5# other than the beginning of a line, it and any subsequent
6# characters will be ignored.  A line in between brackets '[]'
7# denotes the beginning of a ruleset. In the brackets should
8# be a name for the rule and its ruleset number. Any other lines
9# will be considered to be the 'action' part of a rule
10# passed to the devfs(8) command. These will be passed
11# "as-is" to the devfs(8) command with the exception that
12# any references to other rulesets will be expanded first. These
13# references must include a dollar sign '$' in front of the
14# name to be expanded properly.
