Very Small Rom
« on: April 16, 2006, 04:07:01 pm »
Does Linux 2.6 and GPE/OPIE really fit in the small 16MB ROM of the Zaurus 5500G. And is it possible to install programs and/or put data on a SD or CF card, perhaps via overlayfs? Or just mount the flash card on e.g. /usr/local to install software?

Actually it's 14MB and not even a ROM

Yes, you can mount cards and either link e.g. /opt or /usr to the card or install via ipkg to a different destination and link all files individually from there.

Thanks to altboot you can even boot from cards and nfs nowadays.

When I install OZ to the Flash-ROM without a flash card, where is my /etc folder located? Is it written to the FLASH ROM or kept in RAM?
And if I want to install software to a SD card, is overlayfs supported so that for example /usr us mounted from the Flash ROM read-only and all changes to it will be written on the /mnt/overlay which is on the SD card. This would make installing software very easy. Or how is this handled by now, with the mount points? I guess with an installed system there´s actually something in /usr so I can´t just move the folder to a SD card, or I have it to be inserted every time.
I want my base system on the ROM and my optional programs on a SD card, if that´s possible. The overlayfs approarch seems the best here.
