NAME
mount_devfs —
mount a device file system
SYNOPSIS
mount_devfs |
[-o options]
node |
DESCRIPTION
Themount_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
jailyes andjailno 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 jail,ruleset=default.rules
