I\'m using a sightly modified TKC Rom1 image. It\'s got the version of /root/etc/rc.d/rc.sysinit script that I sent to Proto for the tkc rom 2 alpha3 build, which allows including an additional rc script from the SD card on bootup. This in turn allows the creation of home-on-sd, which is reversable (boot without the SD card, an your home is in ram, with the specially prepared SD, you get home on SD).
This has also allowed me to put the OZ contents on an SD card, and with a bit more tweaking, I can mount the SD as root and dual-boot between the TKC rom and OZ.
