I've had some success with Jailbait on my IA1 but I wanted more! Midori Linux http://midori.transmeta.com has a more recent kernel, is under active development and has a cool, web based configuration and build system. And its intended for internet appliances.
The standard setup is intended for Crusoe processers and a full build seems to be too large for the 32MB CF I was using. I changed the build parameters to be close to the Jailbait config setup, dropped Netscape and a few utilities and it builds and installs onto a 32MB CF. I will post my current build file if anyone is interested.
How far have I got? Well it boots, sees the devices and fails to mount the root filesystem. It's trying to read a cramfs from the /dev/hda1 device (the internal CF) which naturally doesnt work. This is because the current version of Midori really doesnt know how to boot from anything other than hda even when IMAGE_DEVICE is set to /dev/hdc. It doesnt even create the dev entries for anything other than hda (I fixed that, but it still has the same problem - there is something else still hard wired).
Note also that it doesnt always boot (this also happens with Jailbait). Sometimes I have to power on/off several times before it boots.
Has anyone else tried this distribution and got any further?
