The other option would be to change uid/gid for all files and modify F15

I guess 'chown -R newUID:newGID ~/*' would be the wrong way to do this,
if there are files with other values for oldUID/oldGID?

I pretty much did that when moving from F14 to F16. I backed up my /home
volume and did a clean install of F16. This box originally started life
as F9 and had been yum upgraded ever since.

After installing, I restored my files to the /home partition and more or
less did something along the lines of:

find /home -uid 500 -exec chown ian '{}' \;
find /home -gid 500 -exec chgrp ian '{}' \;

Where the uid and gid values are my old ones. You probably want to do
that in all locations where you know you've stored files or the brute
force approach and start from / but be careful if you have network
mounts etc.


Thanks for the answers, Patrick and Ian. I guess I'll just get the
uid/gid changover done now instead of waiting for the next Fedora. It
must be done at some point anyway.

Sorry to drag this on a bit more...

The move from F15 to F16 {u,g}id will work without problems, I think. I
may have been a bit unclear about installing F16 in a separate partition
set, while keeping F15 as well in its old partition set, both having
access to the same files in a common partition set. While I think that
the move from the old to the new uid/gid numbers will work for F16 and
access to user files in F15, my uncertainty revolves around whether
there are other things that could be a problem when changing the uid/gid
for an existing account in F15, e.g. files in /etc or other places that
might need to be modified as well. (I know /etc is not supposed to hold
user specific info; just using it as an example).
