interface, and statically link them to the programs using them.
These functions, upon reflection and discussion, are too generically
named for a library interface with such specific functionality.
Also the api that they use, whilst ok for private use, isn't good
enough for a libc function.
Additionally there were complications with the build/install-world
process. It depends heavily upon xinstall, which got broken by
the change in api, and caused bootstrap problems and general mayhem.
There is work in progress to address future problems that may be
caused by changes in install-chain tools, and better names for
{g|s}etflags can be derived when some future program requires them.
For now the code has been left in src/lib/libc/gen (it started off
in src/bin/ls).
It's important to provide library functions for manipulating file
flag strings if we ever want this interface to be adopted outside
of the source tree, but now isn't necessarily the right moment
with 4.0-release just around the corner.

string to u_long and back using two functions, flags_to_string and
string_to_flags, which co-existed with 'ls'. As time has progressed
more and more other tools have used these private functions to
manipulate the file flags.
Recently I moved these functions from /usr/src/bin/ls to libutil,
but after some discussion with bde it's been decided that they
really ought to go in libc.
There are two already existing libc functions for manipulating file
modes: setmode and getmode. In keeping with these flags_to_string
has been renamed getflags and string_to_flags to setflags.
The manual page could probably be improved upon ;)

worthy instance of the latter case was the inversion of -E and -V in the

Turn off setgid-kmem for /bin/ps, it's now quite functional without it.
ps no longer needs /dev/*mem or /proc. (It will still use some /proc
files if they are available for -e, but it's not required, so it'll
happily run in a jail or chroot).
The proc stats are now part of eproc (obtained via sysctl) and no longer
needs to beat up the u-page reading code and the problems with that.
This also has the side effect of disabling 'ps -e' for normal users
*EXCEPT* when looking at their own processes. ie: they can see
environments in processes with their uid, enforced by the ownership of
/proc/*/mem. Root can still see them all, as it can open all /proc/*/mem.
This fixes some nasty procfs problems for SMP, makes ps(1) run much faster,
and makes ps(1) even less dependent on /proc which will aid chroot and
jails alike.
To disable this facility and revert to previous behaviour:
sysctl -w kern.ps_arg_cache_limit=0

be ignored by default by the df(1) program. This is used mostly to
avoid stat()-ing entries that do not represent "real" disk mount
points (such as those made by an automounter such as amd.) It is
also useful not to have to stat() these entries because it takes
longer to report them that for other file systems, being that these
mount points are served by a user-level file server and resulting in
several context switches. Worse, if the automounter is down
unexpectedly, a causal df(1) will hang in an interruptible way.

This is a conservative change. It does the same thing in weird
cases like the old one. For example, 'sleep abcd' still sleeps
for zero seconds. `sleep 10.a' and `sleep 10.05aa' do the best
and not abort (ie: 10.a == 10 seconds, 10.05a == 10.05 seconds).

rm must not use FTS_NOCHDIR, since chdir'ing is required for removing
deep directory trees and the ability to remove such trees is required
by POSIX.2 and POLA. The breakage didn't make much difference until
recently, since fts(3) didn't work in deep directory trees. It isn't
clear whether using FTS_NOCHDIR ever fixed anything (Net/2's rm.c is
similar to Lite1's). Perhaps it was actually to limit the damage
caused by the fts bug.
BDEification process of dd(1). Most of the changes are from BDE's archive.
Support for negative offsets is gone again, but the case where you
lseek() onto byte -1 of something from a negative offset using seek/skip
is fixed; if you end up on -1, you won't get a false positive lseek failure.
The biggest changes are to data types (more size_t, for instance) and
argument parsing. skip/seek on /dev/{,k}mem now occurs (instead of "read
until you reach the offset") due to mem devices now being D_DISK. Some
const things are now correctly declared as such, and the "case table"
building is better. The only thing that seems to be left to make dd(1)
everything TOG wants it to be is l10n.

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!
