exactly the same functionality via a sysctl, making this feature
a run-time option.
The default is 1(ON), which means that /dev/random device will
NOT block at startup.
setting kern.random.sys.seeded to 0(OFF) will cause /dev/random
to block until the next reseed, at which stage the sysctl
will be changed back to 1(ON).
While I'm here, clean up the sysctls, and make them dynamic.

Zsh users can add the following to their .zshrc for sysctl completion:
function listsysctls {
case $1 in
*.*) set -A reply $(sysctl -AN ${1%.*}) ;;
*) set -A reply $(sysctl -AN) ;;
esac
}
compctl -K listsysctls sysctl
While I'm here, brucify the getopt() switch.
This makes "mkdir /nonexistant/foo" complain that /nonexistant
doesn't exist rather than /nonexistant/foo which doesn't make much
sense.

implement memory fences for the 486+. The 386 still uses versions w/o
memory fences as all operations on the 386 are not program ordered.
The 386 versions are not MP safe.
it at boot time closer to the way we want it to be in the final version.
* Move the default directory to /var/db/entropy
* Run the entropy saving cron job every 11 minutes. This seems
to be a better default, although still bikeshed material.
* Feed /dev/random some cheesy "entropy" from various commands
and files before the disks are mounted. This gives /dev/random
a better chance of running without blocking early.
* Move the reseeding with previously stored entropy to the point
immediately after the disks are mounted.
* Make the harvesting script a little safer in regards to the
possibility of accidentally overwriting something other
than a regular file.
not yet been caught), don't save the config with a null drive
name (which causes the drive to be renamed "plex" on the next
start), put in the text "*invalid*" instead.
This is damage control, not a fix.

Break some long format strings so that they fit in style(9)-sized
lines.
Remove some "outdentation".
then all packages would be deinstalled!
The tightening up of version number checking also fixes a bug where
a package file such as gtk.tgz would have resulting in gtk-engines
being deinstalled.

- Terminate ki_mtxname with a null char rather than ki_wmesg.

supported since it's not easy to put 3 bytes accross 64Kb windows
of memory. This should not be such a problem with linear framebuffers.
There is no major interface modification except that the color type
becomes u_long instead of byte. So one just need to recompile his
application.
