work with the delta. Deltas are normally about 10% of the full rpm, so
that you double the needed space if you keep 10 deltas per package.
AFAIK, SUSE delta RPMs donĀ“t require the presence of the full,
original, binary RPM.
Instead, the delta RPM can patch the needed files on the fly, directly
onto the filesystem. In fact, they are not exactly deltas between
complete RPM packages/files, but patch RPMs (or deltas for individual
files inside an RPM package).
