On shutdown, I (seemingly intermittently) get this message on both musl and glibc installs.
dinit: Could not load service nscd: service description not found.
I cant find any reference to this service by grepping the relevant directories, hence calling it a ghost service :)
# grep -rsin 'nscd' /usr/lib/dinit
# grep -rsin 'nscd' /usr/lib/dinit.d
