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?
