++# Have pkg create the repo such that each package is named with the short hash
++# of its file contents in the package filename, with symlinks to the traditional
++# package filenames. The packagesite.yaml file will point to the hashed version
++# of these files. By using hashed pkg filenames, this allows users to lazily
++# cache packages without conflicting with the existing packages, or serving stale
++# packages from a cache. Once the packages are synced the much
++# smaller meta files can then be synced. Allowing a near atomic update of the repo.
++# On caching CDNs this means a need to purge 2-5 files instead of all pkgs that
++# have been updated.
++# The symlinks are only required for the local poudriere for resovling dependencies,
++# they do not need to be uploaded to the CDN.
