The zchunk advantage over deltarpms is much less CPU usage, while its
disadvantages are slightly larger network usage and increased disk
usage.
Note that for most users the increased disk usage is temporary, since
rpms are deleted after install.
If they're deleted after install then surely next time there is an
update there won't be any local chunks and everything will have to
be downloaded?
That's what has been confusing me about this whole thing - as I
understand it the idea is to only download new chunks and to reuse
chunks that are unchanged from earlier revisions, but it seems
that doing that would require keeping a local copy of every
installed rpm which would be a big change that nobody seems to
have mentioned.
