Yeah, and when MS screws up with one of the master keys
(or some hw wendor) think about the "dual-booters"

Microsft pushes revocation key through windowsupdate, and you
suddenly find out your linux wont boot anymore, beacuse the
signature that is supposed to validate your boot has been

Or a "local dos": just add a single byte to the end of some
of the signed files/images and the signature checks fail,
ending up with non-bootable system.... you dont even need
to exploit it further....

Or MS alters license rules around key signing, so when your
key expires, guess what... and ms wont be in a hurry to fix
it.... look at the time it has taken so far for linux foundation
to try and get proper signatre key....


There is so many fun ways to screw up this "security illusion",
that it should be buried & forgotten already...

this "secure boot" pushed by ms is also in reality a ms-restricted boot...
