It seems to me there are that things that are not be handled by rsync
-a, namely acls and extended attributes and SELINUX context too. At
least.

>From a little googling it seems GDM at least changes ACLs of some things
so maybe that's the problem? Some use of getfacl might show differences
in ACLs. I don't really understand the /tmp writing issue though.

Anyways, I usually image when cloning drives. Either partition by
partition with partclone or whole disk with dd, possibly doing file
checksums before and checking after to make sure.
