Oh, also: why would you need efivarfs mounted to read a kernel parameter? Wouldn't that be in /proc/cmdline?

Initrd, initramfs, potato, potahto.

I was thinking of the case where UEFI is booting an EFI enabled Linux kernel directly without an intermediate bootloader. In that case one way to pass data to the initramfs image is through EFI variables.

You can of course rewrite the boot entry to set the kernel command line but it seems safer to use other variables to reduce the risk of becoming unbootable.
