Hi.

Why? We have plenty of history of having multiple implementations of
things (slub, slab and slob...).

That's just wrong. TuxOnIce deliberately doesn't remove any of swsusp or
uswsusp so that there's no chance of users having regressions. It
provides the _option_ of being a drop in replacement for swsusp, but it
doesn't force users to take that option.

Regressions happen at the moment because TuxOnIce isn't included in
vanilla. Users update from one version of stable to the next or from one
version of head to the next and expect TuxOnIce to keep working, and it
doesn't always do that because of changes to the vanilla code that
require an updated patch.

If there are features in swsusp that TuxOnIce is lacking, or features to
uswsusp that TuxOnIce is lacking, please tell me what they are and I'll
implement them. In saying this, I don't deny that TuxOnIce code can
still be improved - there's a lot I'd still like to do.

Nigel
