Recently I did a sysupgrade on an older OpenWRT system and upgraded it to LEDE. I had the problem that there was no dnsmasq user because /etc/passwd is in /lib/upgrade/keep.d/base-files-essential and sysupgrade does not merge them. I thought a bit about how to improve this.
There is a NSS module called nss_altfiles [1] that allows to have a secondary /etc/passwd, /etc/group and so on files at an alternative location like /lib/passwd or /lib/group. OSTree also wants to store an additional /etc/passwd in an alternative location [2]. systemd has systemd-sysusers that is also used for stateless systems with systemd [3]. I wonder if LEDE could not have a similar mechanism. BusyBox and musl could be easily changed to look in a secondary location and it should be easy to mimic systemd-sysusers.
