What's your thought on how to solve this libsystemd-shared issue should
we consider splitting out systemd-{sysusers,tmpfiles}

- link statically (and carry a downstream patch for eternity)
- move libsystemd-shared to systemd-utils and risk the breakage that can
result from a partial/aborted upgrade
- copy, instead of move, the binaries + libsystemd-shared and make the
resulting systemd-utils package Conflict with systemd (instead of having
systemd depend on systemd-utils)
- something else?

Regards,
Michael
