So this is an idea to replace our current hibernation implementation with
TuxOnIce.

Which unfortunately I don't agree with.

I think we can get _one_ implementation out of the three, presumably
keeping
the user space interface that will keep the current s2disk binaries happy,
by
merging TuxOnIce code _gradually_.  No "all at once" approach, please.

And by "merging" I mean _exactly_ that.  Not adding new code and throwing
away the old one.

While I can work on creating one hibernation implementation by taking the
best ideas from all of the implementation we have at hand, I surely won't
be
working on replacing our current code with TuxOnIce.  If that disappoints
you,
then I'm sorry.

Best,
Rafael
