It's hard to tell precisely. FLAVOUR is not assigned any value in
library.sh explicitly AND "$FLAVOUR" apparently evaluates to "" at
line 352[1].

I have never said they are. I only gave the postinst script as an example
of a place where FLAVOUR is assigned. Do you know of any other place?

Then what is in your opinion KERNEL_FLAVOUR for? It can't but ask why
there are two variables with apparently the same value (or at least
values from the same set).

I will try the fix suggested by Martin Michlmayr and see if it works.
