-Subject: [PATCH 4/4] opkg_download: Use short cache file name
-
-Source URIs can be very long. The cache directory itself may already have a very
-long path, especially if we're installing packages into an offline rootfs.
-Therefore it's not a good idea to simply tag the source URI onto the cache
-directory path to create a cache file name.
-
-To create shorter cache file names which are deterministic and very likely to be
-unique, we use the md5sum of the source URI along with the basename of the
-source URI. The basename is length limited to ensure that it the resulting
-filename length is always reasonable.
