9bdd3e8497 Added the convenience "distribution" target which calls the
target of the same name from src/etc/Makefile with a proper
environment, suitable to be used during upgrades and cross-
builds.

79653046d8 Add a new sysctl, "security.jail.chflags_allowed", which controls the
behaviour of chflags within a jail.  If set to 0 (the default), then a
jailed root user is treated as an unprivileged user; if set to 1, then
a jailed root user is treated the same as an unjailed root user.

This is necessary to allow "make installworld" to work inside a jail,
since it attempts to manipulate the system immutable flag on certain
files.

8bac4dbf71 Add a warning note to security.jail.allow_raw_sockets
about the risks of enabling raw sockets in prisons.

Because raw sockets can be used to configure and interact
with various network subsystems, extra caution should be
used where privileged access to jails is given out to
untrusted parties. As such, by default this option is disabled.

A few others and I are currently auditing the kernel
source code to ensure that the use of raw sockets by
privledged prison users is safe.

927b481001 o Implement -U flag: run command as user which exists only in jail.

a5ca5c1a75 A variety of content cleanups:
(1) Document the notion of using jail(8) to run "virtual servers" or
    just to constrain specific applications.  If only running specific
    applications, some configuration steps are unnecessary (such as
    editing rc.conf).

(2) Add some more subsection headers to break up the bigger chunks of
    text.

(3) Clarify the problems associated with applications binding all IP
    addresses in the host, and attempt to be more specific about
    potential application problems.  Document how to force sshd to
    bind the the right socket.

(4) Suggest that in a jailed application scenario, you might want to
    have the host syslogd listen on the socket in the jail, rather
    than running syslogd in the jail.

(5) Catch another reference to /stand/sysinstall.

d82dae3ec9 When pointing users at mount_devfs to populate the /dev of a jail,
tell them that they also need to use devfs rules to prevent
inappropriate devices from appearing in the jail; add an Xref.  In
earlier versions of this man page, the user was instructed to use
sh MAKEDEV jail, which only created a minimal set of device nodes.

723f7e3025 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.
