After a successful up2date frpm Fisher to Wolverine, /var/spool/up2date still contained the headers to the kernel packages. I was told that up2date should remove all excess files on completion.
header files are only removed after a succesful package installation. Since the kernel packages were not actually installed, the headers werent removed. I suppose it's debateable if this is desired behaviour or not, but as far as I'm concerned, it's working as designed. other opinions welcome...

desired behaviour, these are cached.
