Add new commands to rc(8): describe and extracommands

[lme]

Summary

The patch adds to new commands to rc(8). This is what can be done with it:

$ service sshd describe
Secure Shell Daemon

$ service sshd extracommands
configtest keygen reload

It also adds a "descr" variable to sshd's rc script and documents the additional rc options. See https://phabric.freebsd.org/D451 how to print them using service(8).

Can you also update share/man/man8/rc.8? The "Each script is expected to support at least the following arguments" section.

Really like this idea, think it was discussed a while ago?

[lme]

Update the rc(8) manpage and add descriptions to most rc scripts in /etc/rc.d/

Please commit in 2 separates commits: 1 the tools, 2 adding the descriptions

Consistency, filesystems or file systems? Not sure which we prefer these days, but pick just one. After going through the whole patch, "filesystems" seems to be more common.

etc/rc.d/gbde

GEOM

etc/rc.d/netwait

"the network being up"?

etc/rc.d/nfsuserd

Sounds a bit strange, "and" instead of "plus" maybe?

etc/rc.d/nscd

"name service" here, but "name-service" below. Pick one.

etc/rc.d/quota

16

lowercase "check"?

etc/rc.d/virecover

sessions

etc/rc.d/wpa_supplicant

Does the script work for wired interfaces as well?

• Integrate most of brueffer's suggestions. While here, change the remaining "file system" to "filesystem". Most of the description comes from the daemon's manpage which are not very consistent.
• Always allow to run "describe". Having to use "onedescribe" feels just wrong.
• Add the now keywords "describe", "extracommands" and "oneextracommands" to the tcsh completion examples
