I just did a stage3 install on a dual core arm (a hardware I designed using a Cyclone V SOC).

I got it working pretty well, but there is no console with the stage 3 tarball.

This is the depgraph for elogind:

Sorry, but it is a bit of mess of a question, you have piled many issues in one.

What are you trying to achieve, console only system without graphics environment and without elogind ? The setting USE='-elogind' should do the trick. You should also get rid of polkit (the only package which unconditionally requires elogind on my system, at least), which should be possible if you do not use udisks, and upower

RayDude,

What does "no console" mean?
You can't log in, the screen is blank, the keyboard doesn't work?
Note of the above?

Thanks Neddy, dmpogo, cboldt.

This is an embedded system: no keyboard, no monitor, no USB, just a serial port and two ethernet ports.

RayDude,

What do you have in /etc/inittab ?

The default is

Not much needed to get a console, certainly not consolekit, polkit, dbus, or elogind.

Neddy has you on the right track. I'm surprised default /etc/inittab has all the getty's commented out!

Curious what you use to monitor with. I've used displayless laptops as server, and just ssh in with another machine providing keyboard and console - never crossed my mind to use serial port, USB, whatever.

Yep!

You guys are right. I didn't understand how it worked.

My serial port is simply /dev/ttyS0, I think and it looks enabled in inittab, but I think the baud rate is wrong. I'll figure out how to configure inittab now.

Imagine using linux all these years and not needing to learn this before now.

THANKS MUCH!

RayDude,

ssh in, install minicom and do a loopback test on the serial port.

Turn off all handshaking, link the Tx and Rx pins together anh see that anything sent to the serial port comes back.
That proves most of the kernel setup. It will work at any baud rate, unless you can configure your arm system to do split baud rates.
Split baud rates were never a thing on the PC due to a design error by IBM.

To get kernel messages on the serial port, yon need to pass something like

I haven't had a chance to reboot and prove the serial console is working, but my other dependency issues went away as soon as I removed elogind from USE.

Thanks again for your help.
