Bug#943392: Output to both tty0 and ttySX shouldn't be using plymouth

[Thomas Goirand]

Package: systemd
Version: 242-7
Severity: important

Dear Systemd maintainers,

If one wants to have the boot process displayed on both tty0 and on the
serial port (ttyS1 in my case) AND have the services show, then the way
to go is to install Plymouth, eventually with the "nosplash" option on
the command line to avoid displaying a logo.

For example, the grub command line would be:

nosplash text console=tty0 console=ttyS1,115200 earlyprintk=ttyS1,115200 consoleblank=0 systemd.show_status=true

Unfortunately, this concept is broken by design. Indeed, plymouth is far
from being the first .service to start, and as a consequence, a lot of
the output is just missed on tty0.

If there is a way to configure systemd so that it output behaves correctly
(and by correctly, I mean as sysv-rc did for DECADES), please let me know,
and my appologies in advance. Though I've searched the web for a long time,
and what I describe is I believe correct. If I'm correct, then please
report the problem upstream and get this fixed.

Thanks for maintaining systemd,
Cheers,

Thomas Goirand (zigo)
