But on re-installing the system
(which had been in operation for several years)
I found my UID had changed from 500 to 1000.

I dealt with this by chown -R, which worked fine.

I've just gone through a similar change, when installing a newer release
into a LAN with mixed releases, and wanted the same usernames to have
the same UIDs and GIDs, everywhere.  It just makes things so much
easier.

I decided to change the older release up to the newer IDs, rather than
fight against the system.  So, in my case, on the older system, I:

edited /etc/password to change my old UID from 500 to 1000
edited /etc/group to change my old GID from 500 to 1000
chown -R tim:tim /home/tim/
chown tim:tim /var/spool/mail/tim

Just a note to say that I followed this advice,
and it worked perfectly.
Thank you.

In the future, you could also do:

# find / -uid <your-old-UID> -gid <your-old-GID> -exec chown tim:tim \{\} \;

Example:

    # find / -uid 500 -gid 500 -exec chown tim:tim \{\} \;

That will find any file on the system that's owned by user 500 and
group 500 and change its ownership to user "tim", group "tim". Quite
handy for this activity and ensures you don't miss anything.
