Then it fails with "/bin/sh not found".
As new_root is mounted (/bin/sh is there in the initrd), where /bin is a symlink to /usr/bin, this should be obvious...
You also did not provide any error message or other pointer which would lead us to the source of your problem, and I think you should add anything you have (eg. remove the "quiet" boot option).
I have to admit that I did not think about removing "quiet" this morning:-/ Shame on me.
My question is basically how to get the a debug shell in an initrd created by mkinitcpio with the "systemd" hook enabled?
The long and involved way is most likely to make sure the systemd-debug-generator will be added to the initrd by the "systemd" hook, together with a modified debug-shell.service that actually is started during the initrd (and not only afterwards).
Then I should be able to enable that debug shell with the kernel parameters documented for the systemd-debug-generator.
Is there a simpler way, involving less hacking?
With /usr not correctly mounted, you might want to check fstab and arch-chroot to the current setup and try mount -a? Maybe somehow pull busybox into / before you chroot, so you have everything you need while in the dark ages...
