And, as a variation on this question, is there any easy way to correct 
the situation when it is wrong?  I am always having to chmod 777 things 
to be able to complete copies or whatever over nfs, and then to chown 
-R places I`ve worked so that files are not owned by messagebus just 
some number.  It is a mess that I have got used to, but would like to 
sort out.  But how would I find all the files owned by me, for example, 
to change them to an altered UID.  And is editing /etc/passwd enough to 
alter a UID -- I seem to remember there is another database as well.

Perhaps someone has written a script to do this?
