In most cases, when the application is a minor release, this should not 
be a problem.

Each distro has it's own scheme for uid/gid.  You need to "remap" the 
uid/gid, when you preserve /home and install a different distro. 

After installing the distro you could have done (as root):
	# cd /home
	# chown -R <username>:<groupname> ./username
where username and groupname are the newly created account and group.
