You need make sure your PC CPU is supported (with SSE3 at least), for

c2d or above is OK and Atom of course.

So far, it's seemed to be a fairly weird collection of architectures.
I kind of expected N900-specific and LPIA builds, potentially + a
generic-as-possible ARM, a highish-power x86, and an amd64 image.
Can anyone comment on the list of architectures meego is planned to
support? Obviously, "ARM and x86" is the general idea, but there's
plenty of potential subdivision within that.
Old ARM, new ARM, lpia, old x86, new x86, amd64 would be my preferred
list ;) - for a weedy netbook or phone, CPU optimisations could make a
noticeable difference to performance.
Presumably, OBS makes building for additional architectures not too big
of a deal - although I realize it increases kernel and testing somewhat.
the big deal is in the amount of build capacity needed and the maintenance and
work
it is to keep track of all this.
on the x86 side, I kinda disagree with your choices.
Every linux distribution to date picks one "start point" in the x86 evolution,
and supports everything after that. Right now, MeeGo uses "Core2Duo" as that
starting point
(which is now 4 years old or so), which includes Atom as well.....
That captures a very large amount of machines out there, while still working
optimally on Atom...
(the SSSE3 choice comes from using SSE not x87 for floating point math, which
helps atom a *ton*, but is
also very good for core2 and later... frankly, x87 is nasty for the compiler
which means the generated
code isn't always so nice)
