Do I understand correctly:
- without the manual step, users will remain on the old format
- with the old format, in F33 everything will still work fine, but
after upgrade to F34, the database will become read-only
Why is an automatic 'rpmdb --rebuilddb' not part of upgrade plan?
To repeat what I said in https://pagure.io/fesco/issue/2360:
I left it open on purpose (note the "probably" in there) as there would
be any number of ways to achieve the rebuild with varying degrees of
automation and opt-out opportunities, depending on what is actually
desireable for Fedora.
One possibility could be adding a rebuild step to dnf system-upgrade
plugin, rebuilding the db after distro upgrades is not a bad idea
regardless of db format changes (at least BDB performance would
gradually degrade unless rebuilt every now and then). That would leave
people doing the (unspeakable) distro-sync upgrade to deal with database
format manually, which might be just the right balance of freedom. Or
not, I dunno. Other possibilities include planting a one-shot service
that does the db rebuild on the next reboot and decommissions itself
afterwards in the rpm package itself. Other variations certainly exist.
Suggestions welcome, just as long as you don't suggest rebuilding from
rpm %posttrans :)
