I changed dbus in rawhide to use the upstream sysusers.d configuration, which prefers dynamic IDs. > I changed dbus in rawhide to use the upstream sysusers.d configuration, which prefers dynamic IDs.
Thanks for the quick reaction. However I don't think that *in this specific case* it is the good way to go.
In particular, I see that the `dbus-daemon` package is shipping a setGID binary at `/usr/libexec/dbus-1/dbus-daemon-launch-helper` owned by the `dbus` group:
```
%files daemon
[...]
%attr(4750,root,dbus) %{_libexecdir}/dbus-1/dbus-daemon-launch-helper
```
After the "dynamic GID" change you just pushed, this binary will now get a different GID on each system where the package gets installed/composed.
This is troublesome for the push towards deterministic/reproducible composes, and it introduces additional issues for transactional systems doing sandboxed/out-of-band composes (where the GID may change across runs).
I pretty much welcome the specfile switch toward a sysusers.d fragment, but I'd recommend sticking to the Fedora allocated UID/GID `81` for that (overriding/patching the upstream content).
(I didn't manage to trace down this ID allocation through history, but I do feel that it may have been requested to cover this exact setGID binary too).
I'm re-opening this one as this impacts all rpm-ostree based variants of Fedora and as Luca mentioned we need to use a static ID as we have SetGID binaries in the package. I eventually found some time to do the packaging changes myself, PR at https://src.fedoraproject.org/rpms/dbus/pull-request/16.
