Hi,

I've already noticed that almost 30G of data is saved on CentOS mirrors (only counting release 4/5, i386 and x86_64 archs), just by using hardlinks for similar packages.

But I have gone further, and checked if something else could be saved, and my hardlink report is this:

Directories 404 Objects 45722 IFREG 45231 Mmaps 307 Comparisons 308 Would link 300 Would save 78958592

Another 300 files, 79Mbytes could be saved. Not as much as what is already saved, but some (38) of these files are RPMs, so it makes me wonder if the hardlink process is not automatic at all, and who should I contact in such cases, if not this list.
