This is expected. It is created as a mount point for the later-to-be
root file system.

The directories are not "made", they just "appear" there by mounting a
file system. Seems this part fails. This happens in mountroot. Try
breaking at "bottom" (that's just after mountroot) and have a look what
is mounted. Your rootfs should be mounted at root. It seems it isn't,
for whatever reason. You might try to mount manually and see whether it
complains.
