What’s so special about passwd/shadow that they need special treatment in for read-only rootfs? What happens when you next want to support changes to /etc/group: do we add another variable for that, or re-use PW_SUBDIR? What about /etc/hostname? This has a scaling problem: it’s solving your one particular problem but not the general problem. Anyway, isn’t this a solved problem by using overlayfs? Ross
