I've mucked around with OZ 3.5.1,2,3, GPE and Opie, Hentges, and Daniel Steen's Rboot, etc, and my problem is this: They all have features I love, but none of them is as good as all of them. Specifically, I'm talking about performance.
Hentges is the easiest to use and the best initial configuration, but running straight off SD (even with 1Gb) it's just not that quick. Command-line mp3 players skip when playing off the SD (and maybe that's just the speed of the card). Not to mention the fact that I have to rerun ipkg-link every couple of installs to make sure everything's linking the way it should. Seems like the Rboot method (using a disk image) runs faster and eliminates the need for re-linking, but the current OZ kernel (openzaurus.org) won't get me past configuring modules before it craps out. (Guess I'm waiting for 3.5.4...) I'd love to boot into an image from Hentges, but I can't get the image built first. So anyway:
1) How would I transfer my current config into a new disk image? Would copying everything into a loop0 mount give me the exact same stuff? Does the rboot "copy" script get everything it should?
2) Looks like rboot's "modify_init" screws up the altboot init scripts.. should I just skip this step and assume altboot will recognize my new disk image? Does it need to be named something different (jffs.something?) or an FS different from ext2?
3) Is there a better FS than ext2 for speed in a disk image? Does it have to be ext2? Why is jffs preferred in the initrd? Does it work better on flash RAM?
4) Would there be any advantage to be gained by creating an additional image for a swapfile (per dropbear)?
I know all the things I'm mulling are really just ways to push the 5500 beyond it's hardware limitations, but someone has to have figured these out by now...
Thanks to all for your help, I've gotten tons of solid advice from the board in the past and you guys (esp Mickey and Mattias) make one hell of a user community.
