Some real world feedback... just now I am trying to fix a bug in my dual tuner video card where using both tuners at once causes problems. One of my diagnostics caused a crash I wanted to capture so I wanted to set up serial console (via IPMI LAN). Having added console=ttyS0 to the Linux command line I started googling to see what I needed to do to get a login prompt. Pre-systemd it would involve changing inittab which I always hate doing because the next update that comes along might also want to modify inittab. It turns out that what I had to do under systemd is nothing. It automatically starts a login prompt on any terminal designated as system console. Now that may not be what everyone wants, and I don't know if turning it off is easy or not, but it's what I wanted, so I'm happy. James
