ok. afaik: the public information mostly deals with the maemo
application sdk. this is why i posted here. i don't want to just raise
the noise level :-)

i for myself am a debian user for over 6 years now. - i am working
exclusively on debian for all my desktop stuff. so i have some
experiences in that. IMHO a general purpose/vanilla debian distro will
not be perfect for that job. I would concenctrate on a streamlined
version, perhaps using an asynchronous init.d (like initng) for
instance. this implies changing the debs, since the debs use the general
purpose init.d right now. perhaps one could build an autmated
translation from the existing scripts files towards a faster process.

this is just on thing I would look at.
another would be a faster hotplug infrastructure.
i think the shell script approach should only be used for third party
hardware - it is costly to probe all that.
it would also be interesting to add some udev specs for mobile devices
(like memory sticks and stuff like that)

as I said just some random thoughts. anyways I'm looking forward to
buying one!

Okay. I'll going to read that.

I've heard that flashs only support a limited numer of writes over time.
Perhaps that isn't the case anymore.

Sounds interesting. Will read about that.
