comments and empty lines have been touched.
All of this should go in the diskless(8) manpage, now if we had
some kind of 'literate programming' tool to extract the comments
from the script and put them in a reasonable nroff format, it
would be a lot easier to keep code and docs in sync
+ SUBDIR.cpio.gz prevents files from SUBDIR/ to be copied when
priming the memory filesystems. This restores the old behaviour
and makes the copy process a lot more efficient
+ look for templates also in the list of directories supplied by
bootp/dhcp via the T134 option aka kern.bootp_cookie
+ keep track of directories temporarily mounted with "remount"
or "diskless_remount" commands and unmount them once we are done
with them (at the end of this script).
Trigger not only on diskless booting sysctls being set, but also
on the existence of the file "/etc/diskless". But do not try to
extract IP# related keywords in that case.
Add a general "remount" facility to allow non-NFS remounting.
Instead, load them as part of the rc.d system. This allows us to prioritize
the initidiskless script so it runs before the configuration files are loaded
and allows us to get rid of the exit 2 hack in /etc/rc. The exit 2 never
worked anyway since it did not unset the prior configuration, causing the
diskless code to not operate properly.
Do a major cleanup and revamping of the diskless code for RCNG. This will
be backported to the non-RCNG scripts as well as -stable.

a per-machine or per-cluster (with different ways of expressing what's
part of a cluster) basis. In order for this to be effective, rc.conf
has to be reread after initdiskless is finished. Implement this by
adding a hook to etc/rc which rereads rc.conf by request. This can
also be implemented by renaming initdiskless to initdiskless.sh and
sourcing rc.conf there manually, but it was decided that, that would
be uglier than a hook in etc/rc.

/etc filesystem isn't enough; consequently, add "-i 4096" to the newfs
command for /etc. This results in 1022 inodes, which should be enough
for the forseeable future (although I don't know why we would ever
have more than 1000 files in a default /etc).

Note, the use of an MFS /var should also be settable.
Otherwise installing ports(packages) is just a total PITA.
the null mount, we currently create a temporary mfs on /tmp, copy
/etc to /tmp, then mount /etc as mfs and copy everything back from
/tmp, then delete the /tmp mfs.
The patch eliminates the temporary /tmp mfs and the subsequent
copying and simply populates the /etc mfs by copying from
/conf/default/etc. This requires that /conf/default/etc contain a
complete copy of all the /etc stuff instead of just overrides. I
don't think that is too much of an extra step in setting up a
diskless environment.
* Provide the ability to make /tmp a memory filesystem independent
of /var. This removes the requirement that /tmp be a symlink to
/var/tmp and this makes the diskless code work with the default
filesystem layout. If a seperate /tmp memory filesystem is
created, the 'tmpsize' environment variable is used to determine
its size (default to 10 Meg).
* Reduce diffs between the -current and -stable versions of these
files to a bare minimum. Only the definition of the shell
function 'mount_md' is different.
