> You can mount RW fs on RO fs. Distributions on Live-CDs do it all the time. Right, but that's with OverlayFS and such, right? (I.e. not just straight bind mounts.) Seems awfully complicated to solve what essentially should be a non-problem... (I'm aware OverlayFS has other uses, but in this instance it seems like overkill.) EDIT: I'll just note, I did say "separate filesystem" (i.e. non-bind), but I guess it might have been easy to miss.

> Right, but that's with OverlayFS and such, right? (I.e. not just straight bind mounts.) Most probably yes, but there are probably distributions using ro rootfs + specific mounts. I think that in many cases embedded devices would use such a scheme instead of OverlayFS. EDIT: But you probably have to mount workdir and upperdir somewhere over this ro rootfs for OverlayFS to work. > EDIT: I'll just note, I did say "separate filesystem" (i.e. non-bind), but I guess it might have been easy to miss. I was hoping that you could read between the lines also :) I mentioned my WIP distribution. I have mounted: - squashfs ro on / - ext4 rw on /mnt/rw - /mnt/rw/var bind on /var - /mnt/rw/home bind on /home

I have mounted: Oooh, burn! :) I honestly didn't see any relevant mention of the WIP-distro you're talking about... but now that you mention it I had a look back. "I am working on Linux distribution" (etc.). > I have mounted:[snip] So... separate file systems.
