I'm able to replicate it on our systems every time, though I have not tried on a fresh install of Debian - our images aren't really that much different anyway.   We don't have a GUI installed, just text mode or whatever you want to call it.  I've spent hours googling and I have not found anyone else affected by this, nor did I find anything in BTS.

I can get a Unicode VT console without any hassle with sysvinit.
I can get my hosts rebooted without fiddling with stty with sysvinit.
I cannot do both (as of jessie) with systemd.

Presumably systemd has its merits, but VT handling is not one of them.
I agree that there're many cornercases in sysvinit's VT handling, but
inability to shut down and reboot is always a touchy subject to me.


But I'm not intending to start a flamewar here (although it's a Friday
night ;), this 'unable to reboot' thing is clearly a minor bug ether in
systemd or jessie's kernel.

I don't know as I never tried that. Either getty is working for me or
I'm booting with init=/bin/sh. But thank you for the advise.
