I have a number of F14 partitions which must be mounted unchanged on the new F16

I use the same user name on both systems but on F14 I got userID 500 whereas on F16
it became 1000. I wasn't aware of that but learned it the hard way. When I chowned
the permissions to 1000:1000 it worked on F16 but now not on F14.

What is the proper way to fix this problem? I am tempted to reinstall F16 and force
my userID to 500, but the system warns me not to create userIDs<   1000. It is not
feasible to clone the partitions due to space constrains so I am not able to have
identical partitions with different permissions.


The "proper" way to fix this is to do it on the F14 system.

Change your password entry to have uid:gid of 1000:1000.  Make the change to the
group file to change it to 1000 as well.

Then, go to all the top of all partitions/directories owned by 500 and chown -R
1000:1000.  In other words, make all the changes on the F14 side.

I had to go through this process when I installed F16 since my RHELv4 system had me
as 500:500 and I NFS mount my directories from there.  Just took 5 or so minutes.

Reinstalls are never needed to change a user's gid/uid.

I thought of this at the very beginning but I never found out how to change userID
from 500 to 1000. Please explain how to do that.


OK....  Let's say that your user name on the F14 system is olsen.....

The entry in /etc/passwd is probably

olsen:x:500:500:Erik olsen:/home/olsen:/bin/bash

and /etc/group is probably

olsen:x:500:

Just change those to...

olsen:x:1000:1000:Erik olsen:/home/olsen:/bin/bash
and
olsen:x:1000:


Why not use the commands "usermod" and "groupmod"? According to the
usermod man page, usermod will modify the ownership of almost all user's
files (but not of the files outside of the user's home dir).

And then....

chown -R 1000:1000 /home/olsen

along with any other directories or file systems that were previously owned by uid
500 gid 500.

As root:

	find / -gid 500 -exec chgrp 1000 \{\} \;
	find / -uid 500 -exec chown 1000 \{\} \;

Cheap and dirty. Will change the UID/GID of hidden files as well.
