Hello Frank, or anyone else affected,

Accepted systemd into bionic-proposed. The package will build now and be

hours, and then in the -proposed repository.

Please help us by testing this new package.  See

to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

mentioning the version of the package you tested and change the tag from
verification-needed-bionic to verification-done-bionic. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-bionic. In either case, without details of
your testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in

N.B. The updated package will be released to -updates after the bug(s)
