Since the change to rc.subr in r198162 it's not necessary to specify
command in the rc.d script if we have a corresponding ${name}_program
entry, which we do for named.
Rename named_precmd to named_prestart to make it more clear and match
convention.
Move the command_args definition related to -u up into _prestart().
It (and the associated $named_uid value) are only used there, and
unlike required_* and pidfile don't need to be used until this stage.
Fix a silly bug that would only have affected people who were using
the new named_wait or named_auto_forward features, AND had set up an
rndc.conf file instead of using the automatically generated rndc.key.
For named_conf:
Add "-c $named_conf" to command_args if it's not set to the
default. If it is set to the default and we're using the base
BIND it's not necessary. If we're using BIND from the ports
the user is likely to have included it in _flags (due to long
necessity for doing so) so don't duplicate that if it's set.
Add $named_conf to required_files
MFC r200563:
The named process needs to have a "working directory" that it can
write to. This is specified in "options { directory }" in named.conf.
So, create /etc/namedb/working with appropriate permissions, and
update the entry in named.conf to match.
In addition to specifying the working directory, file and path names
in named.conf can be specified relative to the directory listed.
However, since that directory is now different from /etc/namedb
(where the configuration, zone, rndc.*, and other files are located)
further update named.conf to specify all file names with fully
qualified paths. Also update the comment about file and path names
so users know this should be done for all file/path names in the file.
This change will eliminate the 'working directory is not writable'
messages at boot time without sacrificing security. It will also
allow for features in newer versions of BIND (9.7+) to work as
designed.

Throughout the network stack we have a few places of

Work around this problem by introducing another "jailed()" function,
jailed_without_vnet(), that also takes vnets into account, and permits
the calls, should the jail from the given cred have its own virtual

We cannot change the classic jailed() call to do that, as it is used
