Subject: [PATCH] Add /usr/lib/rpm/macros.d/macros.rpm-ostree to set %_dbpath
|
||||
to /usr/share/rpm
|
||||
|
||||
We trigger a librpm macro file load in many of our paths. Since the
|
||||
default value shipped by rpm's macro file sets `_dbpath` to
|
||||
`/var/lib/rpm`, we have to explicitly set that back to `/usr/share/rpm`
|
||||
in those paths.
|
||||
|
||||
This became more problematic recently with libsolv v0.7.17 which fully
|
||||
keys off of `_dbpath` to find the rpmdb path to load:
|
||||
|
||||
https://github.com/openSUSE/libsolv/commit/04d4d036b275693a23eef75fba634e7cea2f1a6d
|
||||
|
||||
And it's not technically wrong; we really should make that macro not
|
||||
lie. This is what this patch does by injecting an RPM macro file in our
|
||||
composes which sets it to /usr/share/rpm. So then e.g. the `rpm` CLI
|
||||
doesn't actually need the `/var/lib/rpm` backcompat link anymore, though
|
||||
there's no harm in leaving it.
|
||||
|
||||
In the future, we should be able to drop this once we move all of Fedora
|
||||
to `/usr/lib/sysimage/rpm` (see
|
||||
https://github.com/coreos/fedora-coreos-tracker/issues/639).
|
||||
|
||||
Closes: #2548

Subject: [PATCH] libpriv/rpm-util: Use /usr/share/rpm for base rpmdb query
|
||||
|
||||
Follow-up to previous commit: we had another path where we made a
|
||||
temporary rootfs and symlinked `/var/lib/rpm` to the base rpmdb. That of
|
||||
course broke now that we inject a macro to point the rpmdb to
|
||||
`/usr/share/rpm`.
|
||||
|
||||
Rework this to use `/usr/share/rpm` since that's our canonical location
|
||||
for now, but also add the compat symlinks so that this logic should keep
|
||||
working even on trees without the injected macro yet.
