Makes sense. We can always revisit this at a later point, if one method starts to emerge as the preferred option for most people. > However, I see room for some collaborative work that then can happen in > Yocto/OE: > * carrying local system configuration changes across system > updates: I find it promising to investigate the "stateless" > concept and have started some exploratory work, see > > https://wiki.yoctoproject.org/wiki/Stateless#Status_and_goals_for_.22stateless.22_in_Yocto > (more on that soon) What's the relation (if any) between this and a read-only rootfs? Also this may be only vaguely related, but I have it in my queue to finish the built-in partitioning of rootfs images [1], which will help divide the filesystem into a stateful and a stateless part. The wic part is done [2], but ext4 images are not covered yet. [1] It works by choosing which sub directories of the complete rootfs you want on each partition.
