[SOLVED] How to view logs from early userspace

I am getting some large and scary message at some point in early userspace but it scrolls off-screen too quickly for me to see it.

How can I view the logs from early userspace to see what the error was?

Does your system have a good old fashioned serial port?  If so, you can set up a serial terminal. https://wiki.archlinux.org/title/workin … al_console and capture the data with a separate computer.

Or, grab your phone and use the camera to record it.

It's a laptop so I don't think so. It has USB of course. Could I use my Android phone as the serial terminal?

Camera might work if I can pick out the frame in a video.

Thanks for the hints.

Phone camera worked. Something about the root not being mounted rw. I fixed it.

Thanks for the suggestion. Marking solved.

You can pass "rd.log" to kernel command line and see early logs in journal and dmesg. See mkinitcpio variables.
