[Rpm-maint] [rpm-software-management/rpm] [RFE] Allow RPM to read chained databases (Issue #1885)

[Florian Festi]

Surprisingly this is not the first time this has come up. The answer still is: "yes, with some - but not completely unreasonable - amount of work." The caveat also still is that just reading multiple databases is not enough to create a useful feature. This starts to become interesting when you are trying to change (or more likely - replace) the base database that comes with the system image, chroot, snapshot, whatever. This may break packages in the system/user/local/upper layer(s) RPM DB. So one needs to check for this and - and that's the hard part - offer the user a way to deal with these errors.

So far the the answer to questions like this has been to copy the rpmdb from the base image and apply local changes to that. Yes, it does not allow swapping out the base image. But it does make all the problems that comes with that go away.
