Of course kenv is available on all platforms - it's the underlying
mechanism for tunables!  However, it does not vary from one boot to
another, or even from one machine to another if they run the same
FreeBSD version with the same device.hints and loader.conf on the same
hardware configuration.

(with the possible exception of a serial number if the SMBIOS provides
one, but I have a room full of identical servers which all have serial
number 123456)
