Would be better to extend agetty(1) to read console name from kernel
command line rather than introduce a special wrapper?

Something like:

   agetty --detect-console [baud_rate...] [term]

Note that in login-utils/sulogin-consoles.c we have code to detect
consoles for sulogin, for example detect_consoles_from_cmdline().

We did a lot of work to consolidate and clean up agetty and kill
things like mingetty in last years. So I'd like to have only util,
especially if all the magic is just console name only.

yeah, that's probably a generic issue.

BTW, I guess that systemd does not use hardcoded console names (like
/etc/inittab), ... just for the record :-) (I have no problem to
support classic inittab.)
