Yes and no. We do use hardlinks, however the mechanism that gets it
from PHX to Raleigh is Netapp snapmirror, which works at the block
level. I don't know enough about snapmirror to know if it is helped by
hardlinks or not. The individual files aren't the real problem, it's
the isos, particularly the live isos.
A program similar to Jigdo could speed this up. Transfer only the RPM packages
(taking advantage of hard links) and information on what packages are in each
ISO image, and then recreate the ISO images at the destination. That way each
package would only be transferred once, regardless of how many ISO images it
occurs in.
