[systemd-devel] How to get systemd boot messages on serial console and screen?

[Frank Steiner]

Hi,

when adding "console=tty0 console=ttyS4,115200" as kernel parameter
on my SLES 12 systems I get all kernel messages both on the physical
screen and over the serial console.
But the systemd messages about the services started appear only on
ttyS4.

When I switch the order, i.e. tty0 after ttyS4, I still get kernel
messages on both, but the systemd messages only show up on the screen.
Gettys are always started on both consoles.

The SuSE support told me I must have plymouth installed and indeed,
when doing so, the systemd messages are printed on ttyS4 and the screen.
But plymouth causes others problems on my systems so I would like
to avoid it.

Is there a way (without plymouth) to make systemd print its boot messages
on all consoles specified in the kernel parameters? From the man pages
and googling around I'm not sure if systemd should be doing this by
default or not.

cu,
Frank
