Hi,
per

I've got feedback about turning RPM scriptlet into systemd service to
have the change applied even on immutable systems, like bootable
containers, Fedora CoreOS etc.
Does anyone use such systemd service for upgrade tasks in their packages?
Would you mind sharing the name of component which uses such service, so
I can check how it is supposed to look?
In general, it's a flawed way to approach the problem.
If it was trivial to handle, it would probably be done by the programs
themselves automatically. If it is not trivial to handle, it is not
reasonable to use a systemd service to do it.
Delayed execution of scriptlets by migrating them to systemd units
also creates problems because it de-links the execution from the
transaction. This means that the risk of breakage goes up depending on
things happening on the system between transaction execution and the
reboot.
My previous attempts at doing stuff like this (like rpmdb-rebuild and
rpmdb-migrate) wound up being fraught with peril (and my fixes never
> were merged, resulting in somewhat broken migrations for years). If
That's a bit thick, Neal. rpmdb-rebuild service as a part of bdb to
sqlite migration was my creation, as git would remind you. It wasn't
perfect but it wasn't "broken migrations for years."
Your rpmdb-migrate was presumably modeled after that. As for the fixes,
we expected the "usr migration" folks to review & merge them, just like
the initial feature was (in my view).
