And this is why Linaro Connects are a bad idea.  They give the illusion
of decisions being taken and finalize, taking the decision process out
of the open source community.

It can be viewed as corporate takeover of open source.  (I realise that
comment is going to get peoples backs up - but unfortunately you can't
call an apple a pear.)

What is the really sad thing is that at no point do the Linaro Connects
really come back to the community (such as this mailing list) and say
"this is what was discussed, and this is what we think, can we get
agreement".  Instead what happens is that stuff gets discussed behind
closed doors, work starts, patches come out, and then it gets discussed
openly.

And... as for the meeting notes system... I looked at the ARM booting
stuff on Linaro's website - it contains no real useful information, it
looks like it's fallen by the way side.  So what's the point of having
a page or two on it?

Tell me then - how is it possible for my laptop to boot correctly with
its ACPI data which describes its hardware, and that ACPI data hardly
ever has to be updated.  Many PC systems have been doing this for
years, with various degrees of success - but generally once you have
a working system it stays working and never needs to have its ACPI data
updated.
