It's Debian-based.  Don't know how it varies from Debian Sarge.

tried editing /etc/fstab by adding the line

/dev/hdb1	/mnt/rh_homes	ext3	rw,user		0	1
 

then: sudo mount /mnt/rh_homes

Still no access because, as you warned, I am UID 500 in Red Hat, and UID 
1000 in Ubuntu.  The inability to su or login as root has me freaked 
out, though.  When I use the gui "Users & Groups" tool [prompts for 
password before launching], and change my UID to 500, I disappear from 
the Users list.  A menu item lets me display all users, and there I am.  
But it makes me nervous.

I did it once before using Mandrake [which made me UID 501].  After 
changing to UID 500, I closed the gui, and from the command line issued 
the command

   # chown 500:users -R /home/arthur

Worked fine, but Ubuntu won't let me login as root, and I don't know if 
I can do anything as a regular user that temporarily has no home 
directory due to missing config files, etc. In other words, if I can't 
log in as arthur, I can't sudo.

The shell includes the regular su command, but it won't take my user 
password as sudo does, and the installation program did not let me pick 
a root password.

I really appreciate the help you are giving me.
