Comment # 14 on bug 937237 from Dr. Werner Fink

AFAICS you *are* working on hvc0 that is that there had been an agetty as well
as a login.  Otherwise the terminal of the grep command would'nt be hvc0.

> Also I don't see system boot output during boot

Wrong order of

   console=hvc0,38400 console=tty0

switch the order to

   console=tty0 console=hvc0,38400 

as with this the last one becomes the main console.  Or use plymouth to see
boot messages on both devices.  There is no blogd anymore and systemd write to
/dev/console which is printed on the main device only.


Beside this I'd like to see

   systemctl status --all dev-hvc0.device
