The system has no way of knowing that bob:uid1 and bob:uid2 are the same
person and in fact on a lot of systems they are not (aka if you downloaded
a tar ball from my box and it had the user bob on it.. it definitely is not
your bob).
The ways to do this are any of the following or a list of ones not there.
1. find ./tree_you_untarred -uid <bob1_uid> -print0 | xargs -0 chown bob2
2. su bob2 (cd /tree_place_to_untar; tar xzvf <file you wanted to untar>)
3. use gnu tar's many options to create the tar file with the correct
uid/gid you wanted using --owner --group (or a map if there are multiple).
