after the post I'm less convinced of this patchset.
What is the meaning of such a left mounted tmpfs in initramfs?
One can't access it afterwards from the new root.

as you can read in the following post mikew also opted for the
strict error http://www.zytor.com/pipermail/klibc/2011-July/003002.html
handling as it is currently done in run-init.

the util-linux switch_root is in contrary very lax, but that
way dev errors can't be catched.
