Yes, it can be done. Two points:
1) I've lost mail from Leopold ... If I remember correctly, the vulnerable
kernels were up to 22.214.171.124. Should 126.96.36.199 be needed? I've not heard about
2) It has often been told on this list that kernel packages provided by Debian
cover most needs, implying that going to compile kernels is a waste of
resources in most cases.
3)It has been repeatedly advised on this list to avoid as much as possible to
recompile and recompile again what may be already available. It is curious
that packages for the most unusual tasks are continuously offered while
kernels not, even in a period of attacks to so many defective kernels.
This is not to object too much to what I know only at the surface. But I am
well aware of energetic problems and multi opteron machines (not to tell of
the equivalent very hot intels) take non-negligible energy to work. Which
also makes the point why going to 64bit for tasks that are equally well dealt
with at 32bit.
You may object that vs a flying machine or even a car (if not missiles and
bombs) a 64bit machine is nearly nothing. You are right.
