I'd have thought that /sbin/init would be a statically linked program. As
it happens, I'm wrong.
/bin/systemd is a dynamic program too.

Now that I'm checking... /bin/busybox is statically linked, but
/usr/lib/initcpio/busybox is not. That is a good incentive to have the
busybox package installed by default. Just in case.

If the system is so borked and you dont have the busybox around, you can
also delete the root=whatever from the kernel command line and you will get
a (initramfs) prompt. Then you can use it as a quick'n'dirty rescue system.
