1)Anyone knows how /dev/null or /dev/zero have been implemented?
2)Ever tried removing /dev/null or /dev/zero and rebooting?
3)How does one recover?

Well, to recover, you will need to re-create the device files. I doubt if insf will create them for you. You can recreate them as follows

mknod /dev/null c 3 0x000002

and

mknod /dev/null c 3 0x000004

# mknod /dev/null c 3 0x000002
# chown bin:bin /dev/null
# chmod 666 /dev/null

# mknod /dev/zero c 3 0x000004
# chown bin:bin /dev/zero
# chmod 666 /dev/zero
