Yeah, I've learned this by now too :) (As in, the bootloader support seems to be included in the cpu subtype support in the kernel..) > Even if you screw kernel flashing, you can still relatively easily > recover using a serial cable (the device needs to be opened though, > which means the warranty is gone). I have done this now :) Actually I havent done the soldering myself, otherwise it wouldn't look like this: http://layer-acht.org/fotos/610_fsg3_uart_2008/100_2190_Sm.jpg.8.html > If something goes wrong when you flash a new bootloader over RedBoot - > well, good luck (there is JTAG, but it's not for mere mortals I guess). I have to thank you for this sentence, the part about the mere mortals. It has become a source of very much inspiration ;-) Though I have to agree, that a "JTAG for dummies" howto will probably not happen in the near future. Or maybe it is possible, for specific devices :-) I'll put my notes about redboot and mtd up on http://layer-acht.org/debian/fsg-3/ tomorrow. > A nice thing on kernel-userland border is adding a custom initramfs: if > your system goes for a lunch and doesn't boot anymore (because the user > just did rm -rf /etc), one can always boot by simply inserting a > "recovery USB-stick".

I'm not sure this is an option for the FSG-3 due to its small flash size. And when you can boot d-i in rescue mode via ssh, I dont see much need for it neither. regards, Holger
