Define "real fork"? Both SuSE and Red Hat have carried patches, in
some cases for years, forward porting them to newer kernels. Does
that make them forks?

SuSE has made changes to e2fsprogs, and carried those patches for
years and years, and even added options to command-line programs which
SLES's init scripts are dependent on --- and this was done without
even consulting me first. Yet you don't see me calling out SLES for
"forking" e2fsprogs and how it "got away" with it.

Can we please cut out this whole forking nonsense? I've been told
that it's only something Slashdot kiddies and ZDNet media types
looking for advertising impressions. Yet you're a kernel programmer,
and one who works for a distribution, and you've made this same claim;
you should know better.

I think part of the problem here is what's considered "acceptable" to
one set of developers may not be considered "acceptable" to another
set. As I've said many times before, what makes sense for a cell
phone battery and highly power-optimized hardware may not make sense
for a devices with 6-cell laptop battery. And I think it's still to
be seen whether or not suspend-from-userspace really is as minor as
people think it is, and what compromises might have to be made in how
app programs are forced to develop their applications, etc.
