You're saying it's easier to replace an embedded kernel than a userspace
file on an embedded system?  Heh, that's funny.

And no, it's not easier to repace a kernel on a "server" than a
userspace file, due to all sorts of good reasons (certifications,
support contracts, etc...)

not accept this kind of patch at all.

Is that final enough for you?
