So fix tar to not do silly things.
Kernel major:minor numbers are not stable.
YOU Tell that to the tar/star people, they are flabbergasted that its not
stable. It apparently is for every other OS tar can be run on.
It's just the new world that we live in.
I don't see us ever going back to 100% static major/minors.
Though as a point of history, Linux has /always/ supported dynamic
major/minor numbers, even back in 0.99 days. We avoided the problem
then because the dynamic major/minors were only used by drivers that had
not yet had static numbers assigned, or their author chose to avoid
LANANA for some other reason.
