Subject: [PATCH] initrd.scripts: kill tuxonice support with a LOT of fire

tuxonice is almost dead. Last update was in 2011 and they're now
trying to resurrect this ugly and non-upstream friendly thing.
Moreover, the tuxonice genkernel code is the ugliest thing I have
ever seen in it. Well no, unionfs was even worse.

So please, let's forget about tuxonice for now and focus on the
good looking code. I am willing to accept patches that restore
tuxonice support if they're good quality ones.

Burn tuxonice init code, burn in hell.
