Missing API in systemd-shim.

Yes. I updated our machines to current 14.10 package levels yesterday (Monday, October 27th) and I'm still seeing the messages on those machines.

I plan to do a fresh install of release-level 14.10 this morning, so I should be able to report whether the messages appear there, too.

Just confirming that I _do_ still see these messages on a fresh install of the released Ubuntu 14.10.

I installed a new system from the current ISO and set up a default user. Upon logging in from the console for the first time:

[ 77.358238] systemd-logind[2499]: Failed to start unit [e-mail]: Unknown unit: [e-mail]
[ 77.358325] systemd-logind[2499]: Failed to start user service: Unknown unit: [e-mail]
