Removed POSIX.1/NetBSD markup (braces) for NAME_MAX, etc. We don't
define this. Most FreeBSD man pages hard-code the limits; in fact,
utimes.2 recently became the only file in libc/sys/*.2 that mentions
NAME_MAX. There probably should be mandoc macros for this.
Text is a compromise based on messages from Wes Peters, Ville-Pertti
Keinonen, and Matt Dillon.

Note: you need to install the current groff tmac macros for these
man pages to format correctly. Specifically, rev 1.21 of
contrib_groff/tmac/doc-syms in -current, or rev 1.17.24 for 3.2-stable
track.
The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;
.\" $Id$
.\"
If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

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...

Unlike other filesystem objects, symbolic links do not have an owner,
group, access mode, times, etc. Instead, these attributes are taken from
the directory that contains the link. The only attributes returned from
an lstat() that refer to the symbolic link itself are the file type
(S_IFLNK), size, blocks, and link count (always 1).
This is bogus, and disagrees with the implementation and symlink(7).
Removed it.
