-# - use a directory + tmpfs via unionfs to build the packages
-# - having only one cache for all the architecture would need a merging before the cache is dumped, this is a bit overkill, so several cache are used, as a consequence the rpm/srpm structure is duplicated. Maybe a separated cache could be done to handle this structure, or just have it created separately. Anyway this is just a mater of some hundreds of kilobytes and directory listings. 
 # - use a cache (rpmctl cache for example) to find maintainer
