I want, essentially, a microcore for ARM, to use primarily with the upcoming RasberryPi. Not for general purpose use, but (mostly) for headless tasks like home server, media centre, music player, home automation, maybe router, etc etc. So i want a bare-bones linux. Microcore would be pretty close to what I want, but there is no ARM version.
What would people recommend as the best choice??
-Stripped down debian
Debian has an ARM version and will officially support rPi, too. But how easy is it to strip it down? (can anyone reccomend a good guide or something?) The default install size is way too big, and i'd guess there are saving to be made re: memory use, too.
-Use a 'router' linux
Like OpenWRT, DD-WRT, Tomato, etc... some areas i'm not sure about with these, but would definitely provide a stable, v. low resources base. I like the possibility of flashing/ external updating.
-Roll my own linux
This would provide a 'perfect' distro, in theory.. but is it practicle? How hard is it?? (again, any guides??)
Is anyone working on this?/considering it? Or has it been done? .. again, i'm not sure of the level of complexity involved compared to 'starting from scratch' (my guess is it would be harder for someone like me, but easier for someone up to speed with TCL dev)
Is there another v. lightweight linux, which supports ARM??
For anyone who hasn't been following it the RPi should be out early next year (as in January; they have finalised the design, made 100 beta boards on the 1st). 128MB ram for the base model.
