Happy newest year, all!

Polite nack.  Let's not make these same changes yet again without 
better documenting our chosen combination and any accepted 
trade-offs.

Otherwise, some frustratingly obtuse half-wit's only going to 
revert them without a proper commit message to fix somebody's bug 
only to re-enable them later to fix somebody's bug, probably:

  https://git.savannah.gnu.org/cgit/guix.git/commit/?id=1dfe8c372163d481ebebb97dd3b4cafa49906b28
  …
  https://git.savannah.gnu.org/cgit/guix.git/commit/?id=6d7e181ba18d11c92409a93936025fb46b9c8171
  …
  https://git.savannah.gnu.org/cgit/guix.git/commit/?id=e49fdc231b0be00490fe1321888eb5c2acc480ac

I'll try to find the context for my reversion in my own logs, but 
it surely broke something.  There may be no way to support all 
users.

I do urge people to test it on kernel-updates, but this is not a 
simple ‘enable CONFIG_FOOBLES to get foobles!’ situation.

Aside: why do we keep adding DEFAULT-EXTRA-LINUX-OPTIONS instead 
of modifying the configuration files themselves?  Maybe this is a 
separate discussion.

Kind regards,

T G-R
