upgrading from sys-apps/systemd-236-r5 to 239-r2
the emerge runs through and warns me that it overwrites files ... so it
merges only partially ...
after that I see:
# systemctl --version
systemd 239
(which is OK)
# eix -I systemd
[U] sys-apps/systemd
Available versions: 239-r2(0/2)
Installed versions: 236-r5
(which is scary)
How to clean that up?
