These can be used to pass extra options to the mdmfs(8) utility,
to customize the finer details of the md file system creation
(i.e. to turn on/off softupdates, to specify a default owner for md
filesystem, etc).
Use these two new flags to mount tmpmfs and varmfs without
softupdates, since it doesn't make much sense to use SU on
malloc-backed file systems.

in /etc/rc.conf.

This improves the truth value of the comment above significantly and
reduces the bogous output on the console considerably.
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.

and looks like no other Unix diskless configuration I've ever seen.
Thus allow a more traditional /etc.
Note, the use of an MFS /var should also be settable.
Otherwise installing ports(packages) is just a total PITA.
md device and file system creation occurs *after* mtree is run, and
as such an /var/tmp/* or /tmp/* entries will be under the mountpoint
(or fail) rather than appearing in the md filesystems. This prevents
the creation of vi.recover, and might affect other localizations that
rely on the mtree calls affecting these directories.
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.

This protects users who insist on the bad practice of copying
/etc/defaults/rc.conf to /etc/rc.conf from a recursive loop
that exhausts available file descriptors.
Several people have expressed interest in breaking this function
out into its own shell script. Anyone who wants to embark on
such an undertaking would do well to study the attributed PR.
