Formatting a Linux disk partition also doesn't change anything in the
EFI NVRAM. Linux (the kernel) provides a filesystem interface to the
EFI variable services. And this (pseudo-)filesystem defines an unlink
operation which performs a 'delete EFI variable' operation. On the
surface, that's not an unreasonable implementation idea although one
could argue that exposing these variables in the filesystem such that
recursive filesystem operations like 'rm -r' can hit them would be
overly risky.
