MOUNT_DEVFS(8)         DragonFly System Manager's Manual        MOUNT_DEVFS(8)

NAME
     mount_devfs - mount a device file system

SYNOPSIS
     mount_devfs [-o options] node

DESCRIPTION
     The mount_devfs command attaches an instance of the device file system
     (or devfs(5)) to the global file system namespace.  This command is
     automatically executed for /dev at boot time.

     The options are as follows:

     -o      Specify mount options, which are a comma delimited set of options
             (see mount(8)).  Supported mount options are:

             jail    Mount devfs(5) for a jail.  Only rules between jail yes
                     and jail no are applied.

             ruleset=rule_file
                     When mounting, apply the rules from the specified
                     rule_file, which can be either an absolute path or one
                     relative to /etc/devfs/.

     Mounting an already mounted node clears and resets all rules that are in
     effect for it and (if a ruleset option is present) applies the rules from
     rule_file.  It is equal to devfsctl -cr followed by an optional devfsctl
     -af.

EXAMPLES
     Mount a devfs(5), marked as jail, with a ruleset file named default.rules
     onto /var/jail/dev.

           mount_devfs -o jail,ruleset=default.rules /var/jail/dev

     A corresponding fstab(5) entry is:

           devfs /var/jail/dev devfs ro,jail,ruleset=default.rules
