This is similar to already asked questions, but the answer has yet to be given.

I fixed up the "openwrt-x86-2.6-ext2.image" so that I can boot it on my MSN Companion and IA1 - Don't start getting Ideas anyone who finds this - I have no plans for framebuffer or other features, just the basic hardware... so its not the next jailbait killer or midori ...

Anyway, I noticed that when I booted the system that root was mounted read/write

I have

rootfs on / rootfs (rw)
/dev/root on / type ext2 (rw)

now what I really want would be something like how (from what I've read) that when a change is made it modifies another partition, and the original is left intact.

I think there is unionfs for this exact thing -but is that supported in OpenWrt (x86) ?

I just want this device to be able to power off at a moments notice, and not worry about having to fsck the main drive.  - if the settings drive gets hosed -- oh well .. redo the setup..

It seems that I can use the squashfs setup for this purpose, I finally answered my own question - I hadn't even looked at either squashfs or jffs2, I ran across it in documentation for other things.

Also seems that there aren't a lot of x86 packages compiled for OpenWrt - I'll probably be building a lot of x86 packages for a few of the minuscule x86 devices I have around.  Perhaps I'll post the binaries for others to enjoy wink

The discussion might have continued from here.
