setup which consists of an NFS mounted archive, the NFS mount was also
used for the tmp space since it had room, and the iso images were
created on the local drive, where it also had room. DOing symlink was
crazy and didn't work too well, and the apt stuff could not be on the
NFS tmp since apt's locking doesn't work on NFS. Problem solved, this
should work exactly like it did before with these defaults though.
COPYLINK basically makes a full copy of the files instead of hardlinking
or symlinking.
