Bug#823346: systemd[1]: system-generators terminated by signal ALRM.

[Alexandre Detiste]

Hum,

That's interresting, I've had the same problem for a while,
but I have had other things to worry about so I didn't investigage it yet.

Here boot hangs at "Welcome to Jessie !" or something  but just pressing any key (PS/2 keyboard)
is enough to make it go further.

Nothing changed in systemd-cron & it has been pretty much "done" for a long time now;
so problem is likely somewhere else. I guess blindly re-assigning it to systemd
won't help (and that already happens so many times).

Same thing here


I'll just this bug open for now.
