Hi folks,

Can anyone think of a good way to implement an installworld /
installkernel seat-belt for source upgrades from stable to current?

What I'm looking for is a way for installworld and installkernel in the
current source to look for some signature in the target filesystem that
suggests that a stable world is about to be upgraded to current.

I want this because far too many people, far too frequently, update
their source to HEAD by mistake and then end up with current when they
really wanted stable. [1]

If this can be done cleanly, I'd like to do it.

If not, I don't want it to be a hack.

So, ideas on infallible signatures?

Ciao,
Sheldon.

[1] Guess who just trashed a stable installation for the 3rd time in 3
    years today?
