I came up with an overall increase of ~ 800MiB
overall including what?
on disk size of the mirrored release image via oc adm release mirror
Also as reported by the mirror command
the main difference in ose-base seems to be that rhel8 bind(-utils) depends on libmaxminddb instead of GeoIP, and in rhel8 the former has a weak dep on very large geolite2 databases (rhel7 doesn't support weak deps, so they probably omitted the equivalent to avoid bloat). let's see if I can figure out how to skip those
We trimmed about 50MiB of on disk pre-compression size from this layer by removing weak deps from bind-utils.
Maybe at some point in the future we should do a broader audit of dependencies we can remove now that we've got a completely different base layer but this seems to have fixed the specific issue from the bug description.
