Modern Linux live CD sometimes produces "panicked at 'called Option::unwrap() on a None value'"

Sometimes, I'll hit this in the beginning of the boot process. Usually it's on the line Waiting for /dev to be fully populated..., or sometimes a bit after. The console produces the following trace:

The image is antiX-21_386-base.iso, available from https://antixlinux.com/download/. It's a modern, no-systemd distro based on Debian bullseye.

Interestingly, when booting this same image in the debug mode, it produces a different message at a different point. It produces Assertion failed at src/rust/jit.rs:481:25: '!is_near_end_of_page(current_address)' - 'TODO: Handle STI instruction near end of page' on Trying to unpack rootfs image as initramfs.... The non-debug version never has a problem with that part though.

I can reproduce both issues.

The first issue is fixed now, thanks for the report.

The failing assertion likely doesn't matter. I will look at it at some point. For now you can comment it out if necessary.

And antiX is working pretty well!
