This works *perfectly* with a read only fs. Each time it boots removes
the non-working serial ports. One could argue that it does NOT work
completely as expected with a writable file system.

This will not work as a post rootfs hook as I've explained before. Let
me give you a more concrete example: We have a root file stored in
flash. We use it to boot from on a system with 4 serial ports. We use
the same image again to boot several kvm instances each of which only
have 1 serial port. The kvm instances will have spurious init messages
about respawning getty.
