Here's what I did.  It may or may not be successful for you - it depends
on how you've set up your filesystems.  I install all of my systems
so that / and /usr are separate filesystems, and the only things on
those filesystems is the FreeBSD distribution.  Everything else
(additional installed software, home directories, etc.) goes on other
filesystems.  Generally speaking, I install with at least the following
filesystems:

	/
	/usr
	/var
	/usr/local
	/home

The goal is to replace everything in / and /usr without touching the
rest.

First of all, back up your system.  I can't emphasize this enough.
I also make backup copies of everything in /etc on a floppy so
that I can meld changes into the new installed versions.

Boot the 2.0.5 installation floppy.  Don't modify the partition map.
After you enter the disklabel editor, assign mountpoints for /, /usr,
and swap.  Toggle newfs on for / and /usr.  All other FreeBSD filesystems
should be toggled to NOT perform newfs.  Either assign mountpoints now,
or later by editing/restoring /etc/fstab.

Proceed with the installation.  

After the installation is complete, copy any files from your saved copy
of /etc that you need.  This would include your password files (pwd.db,
spwd.db, passwd, master.passwd) and fstab, at least.

You might also want to restore some of the contents of /var depending on
your individual circumstances.  Personally, I like to keep at least the
contents of /var/log, /var/db, and /var/mail.

Any comments or improvements on this general procedure would be
appreciatied.
