Hi, I'm preping a new backend for our mirror host, and just found that centos mirror could use a little help from hardlinking. After running `hardlink -cvvn` on our copy of centos repo, I got these results: *Directories 774** **Objects 220535** **IFREG 219740** **Comparisons 4839** **Would link 903** **Would save 2951557120* This means that 903 files are exactly equal (ignoring metadata, like date, perms, etc), meaning that more than 2.9GB could be saved. Hardly much in a 207GB repo, but a save anyway. Also, this means that local file system cache would be optmized. Problem is, everytime I resync my mirror, these hardlinks are lost. So the hardlink shall be done in the master repo. Is there anything that I'm not seeing that prevents this optimization?
