You're not the only one for whom the transition to systemd has been<br>
painful.<br>
<br>
However...<br>
<br>
It *is* possible (some would argue just as easy) to do all things with<br>
systemd that were done with screen.<br>
<br>
For starters, have you seen [1] ?<br>
<br>
Though looking at that again, I realize it could use a section on how<br>
to do pdb - I'll propose something for that. In the meantime, feel free<br>
to find me in #openstack-dev and I can talk you through it.<br>

Thanks,<br>
Eric Fried (efried)<br>
