Aren't changelogs compressed yet ?
I'm very surprised simple flat text data can make such a significant
difference these days (the yum problem OTOH is real but can't yum
truncat the changelogs it exports all by itself ?)
1. we're not just talking about it for yum.
2. I could truncate them in createrepo, sure but the question is why are
we keeping all this stuff on cds in 5 different places and why are we
keeping it AT ALL on the cds.
