I did some searching re UIDs and GIDs, and it appears that the

So, perhaps all you need is a common script that does it for you.
Please do refer to the policy manual re the allocation policy for
Debian.
http://www.debian.org/doc/debian-policy/ch-opersys.html#s9.2
I believe Kailash has given you the answer; the referenced
policy manual says:
-------------------- Begin extract --------------------
100-999:
Dynamically allocated system users and groups. Packages
which need a user or group, but can have this user or
group allocated dynamically and differently on each
system, should use adduser --system to create the group
and/or user. ***adduser will check for the existence of
the user or group, and if necessary choose an unused id
based on the ranges specified in adduser.conf.***
-------------------- End extract ----------------------
[emphasis added :-)]
This sounds like exactly what you want. Set up your initial
system, copy passwd, shadow, group, & gshadow (you probably want to
use tar to simplify keeping owner & group correct), and install them
on each of the other systems. Then do your installs there, and
don't worry about order, because ``adduser will check for the
existence of the user or group'', and use the values already set up
on the system.
Thanks for raising this point, as I keep multiple user accounts
for various activities (general, business, running a charity, ...),
and have been editing the four files by hand to make them match
across OS installations. As Bill Nye doesn't say, ``Nooow I Know!''
