9c97c8f02d Perform a major cleanup of the usr.sbin Makefiles.
These are not perfectly in agreement with each other style-wise, but they
are orders of orders of magnitude more consistent style-wise than before.

3263ed06d8 Change NO_MAKEDEV to a finer granularity method:
NO_MAKEDEV_INSTALL and NO_MAKEDEV_RUN.  The former implying the latter.
The names imply what they do.  The last commit by DES based on a PR defeated
the original idea behind NO_MAKEDEV, which was not to run MAKEDEV, but to do
the installation of MAKEDEV.  This should satisfy both parties on the MAKEDEV
challenge.
Reflect this in the documentation.

ef32330c57 o Replace part-wise instructions for building world for jail(8) with
a simple make world; while this does a bit more work, it means that
  jail(8) doesn't have to be kept in sync with /usr/src/Makefile{,.inc1}
  which is a moving target.  MFC candidate.

89bac1ebf5 Correct mark-up used in rev 1.16, as discussed with its contributor:
* Use a sub-section (Ss) instead of a section (Sh) for
  "Sysctl MIB Entries".

* Use a tagged list (Bl, El and It) instead of sub-sections (Ss) for
  the actual MIB entries.

* Mark paths up as such (Pa).

* Mark defined values up as such (Dv).

c764ef2782 - As jail(8) has been almost completely rewritten, prepend another copyright/
BSD-style license, as an add-on to phk's beerware license.  Please fedex
  some beer to phk.

- Add a ``make depend'' line to the jail-building, which fixes openssl,
  among other things.  Suggested by: kris

- Add ``newaliases'' to the list of things to do when setting up a new
  jail, so that the jailed sendmail doesn't complain.

- Correct references to ``kern.jail.set_hostname_allowed'' which now read
  ``jail.set_hostname_allowed''.

- Add a reference to sysctl.conf where the sysctl can easily be set in
  a persistent way.

- Add a list of cross references to the man page.

- Fix a formatting nit or two.

eeff6080d3 Fix up a few documentation nits in jail(8), as well as improve the

kern.jail.set_hostname to limit jail renamining.

983b65917f Clean up the jail(8) documentation so that it suggests building a jail
userland in a safer way.  Using the NO_MAKEDEV argument in make
distribution prevents the creation of a number of unsafe device nodes
in the jailed /dev, including disk devices, and more.  This depends
on an earlier commit to /etc/Makefile to provide the NO_MAKEDEV
support.

ca21a25f17 This Implements the mumbled about "Jail" feature.
This is a seriously beefed up chroot kind of thing.  The process
is jailed along the same lines as a chroot does it, but with
additional tough restrictions imposed on what the superuser can do.

For all I know, it is safe to hand over the root bit inside a
prison to the customer living in that prison, this is what
it was developed for in fact:  "real virtual servers".

Each prison has an ip number associated with it, which all IP
communications will be coerced to use and each prison has its own
hostname.

Needless to say, you need more RAM this way, but the advantage is
that each customer can run their own particular version of apache
and not stomp on the toes of their neighbors.

It generally does what one would expect, but setting up a jail
still takes a little knowledge.

A few notes:

   I have no scripts for setting up a jail, don't ask me for them.

   The IP number should be an alias on one of the interfaces.

   mount a /proc in each jail, it will make ps more useable.

   /proc/<pid>/status tells the hostname of the prison for
   jailed processes.

   Quotas are only sensible if you have a mountpoint per prison.

   There are no privisions for stopping resource-hogging.

   Some "#ifdef INET" and similar may be missing (send patches!)

If somebody wants to take it from here and develop it into
more of a "virtual machine" they should be most welcome!

Tools, comments, patches & documentation most welcome.

Have fun...
