Re: [Testbed-admins] Changing user Unix UIDs

[Jonathan Walsh <jonathan.d.walsh@lmco.com>]

The changeuid script seems to just change the emulab string username, 
and only for unapproved users.  I wrote a script to do this which I will 
try to send over when I have a chance, but the process is essentially this:

1) Pick a new uid you want that is less than 10000
2) Change unix_uid in the users table
3) Change the uid on boss
4) Change the uid on ops
5) chown all user files in /users and /proj

This works better when there isn't an experiment active for a project 
the user is a member of.
