Createrepo_c in F30 has finally grown zchunk support and I've packaged
up some zdicts that we can use for F30/rawhide, so I'd love to see us
start building zchunk metadata for F30.
To enable zchunk metadata generation, whichever systems are running
createrepo_c/mergerepo_c for Rawhide would need createrepo_c-0.12 and
fedora-repo-zdicts installed. The call to createrepo_c or mergerepo_c
(whichever is run last to generate the final metadata) would need to be
run with the new zchunk arguments:
--zck --zck-dict-dir=/usr/share/fedora-repo-zdicts/f30
Mergerepo doesn't require zchunk metadata in the source repositories to
be able to generate zchunk metadata for the merged repository.
I'm not sure who to ask to turn these flags on, so if there's an
individual I need to ping, please point me in the right direction.
A huge thank you to Daniel Mach for reviewing and merging the
createrepo_c zchunk pull request, Jaroslav Mracek for building
createrepo_c with zchunk, Robert-André Mauchin for reviewing fedora-
repo-zdicts and Neal Gompa for keeping things moving forward with the
PR reviews.
Thanks,
Jonathan
