1. Making the pid symlink now has to happen after named starts, otherwise
it can generate a fatal error.
2. named-xfer is not part of the BIND 9 world.
3. BIND 9 needs a /dev/random in the chroot directory if chrooted.
4. Only the pid file is symlinked now, the ndc socket is BIND 8 only.
5. Create an rndc.key file for the user if one does not exist.
This (generally) allows a BIND 8 config file to be used in a BIND 9
world with little or no modification.

o The parent script, /etc/rc.d/localpkg, passes its command line arguments

o devfs_init_rulesets - Create devfs(8) rulesets from devfs.rules
o devfs_set_ruleset - Set a ruleset to a devfs(5) mount

Additional rulesets can be specified in /etc/devfs.rules.
If the devfs_system_ruleset variable is defined in rc.conf

also be applied post-startup:

This is a more flexible mechanism than the previous method of using
/etc/devfs.conf. However, that method is still available.
Note: since devfs(8) doesn't provide any way for creating symlinks
as part of a ruleset, anyone wishing to create symlinks in a devfs(5)
