* Add mailman to the install process. This includes the package
  install, all the setup needed in ops-install, and the little patches
  we apply locally.

  Note: Only under 6.0: no point in going backwards since its a pain
  in the ass to build these packages for the 4.10 image.

* Push more of the package install back down into the ops/boss install
  scripts. This improves testing within those scripts, and avoids
  duplication. There are some changes in rc.mkelab that will temp
  mount the package dir on /packages for the benefit of the scripts.

tagged from the 6.0 release. Also lots of changes to the install
scripts to handle inatlling boss/ops/fs on 5.4. All changes are
conditionalized so that things will continue to work on 4.10, but
hopefully we will move away from that before the year is out.

actually installed on the images, but this is a good place for it.
Same source configures and builds on Linux as is, so just need to copy
over the source dir to a linux machine and config/build/install.

If someone knows how to create an rpm out of it, that would be great!

Entailed new instructions for manual setup as well as integration into
elabinelab framework.  First, the manual path:

setup.txt, setup-boss.txt, setup-ops.txt and new setup-fs.txt:
    Updated to reflect potential for separate fs node.  The org here
    is a little dicey and could be confusing with ops+fs vs. ops and fs.
    Has not been field tested yet.

*/GNUmakefile.in: new fs-install target.

configure, configure.in, defs-*:
    Somewhat unrelated, make min uid/gid to use be a defs setting.
    Also add config of fs-install.in script.

boss-install.in, ops-install.in and new fs-install.in:
    Handle distinct fs node.  If you have one, fs-install is run before
    ops-install.  All scripts rely on the defs file settings of FSNODE
    and USERNODE to determine if the fs node is seperate.

utils/checkquota.in:
    Just return "ok" if quotas are not used (i.e., if defs file FS_WITH_QUOTA
    string is null.

install/ports/emulab-fs:
    Meta ...

The ports-install script neglects to copy the ulsshblahblah port into
the ports tree, causing mayhem and havoc at remote site.  Updated.

version of the graphics/p5-GD port. This one works with perl < 5.6,
which we need for the moment. This can go away someday when we migrate
to a newer version of perl.

We have a few more sources changes then they do, so we cannot just use it.

into the proper location.
