I just updated to stretch today (from Jessie). Now my system will not start key services. I have RT installed on this system (its primary function), and no one can log in.
I'm getting weird systemd errors at login, but they are not verbose, and I cannot find anymore information on this. I just spent the last 2 hours googling this... find a lot of references, but no fixes.
After booting the system, I log in and get this on the console:
Code: Select all

I have updated a few systems so far to stretch, but this is the first time I have seen this...
I tried booting to the last kernel, and some other boot time options... doesn't help.
I appreciate any help.
