Docker needs to generate a /etc/passwd with uid 0 and the guix build user 
accounts, and a /etc/group with the guixbuild group; and whatever other users 
the things that are composed together using docker compose[1] require.  How 
does this work in Docker-land ?

We need to configure substitute server acls (/etc/guix/acl).  So this one is 
totally our fault.

Docker needs to generate /etc/services with a union of the required services of 
all the things that are composed together using docker compose.

All in all, these are all obvious things which guix-on-docker already works 
around (I don't know the official way that surely exists--hence the 
workarounds).

The question is: since Docker supports composition[1], how do they handle this 
standard case ?  How can we get Docker to generate /etc/services, /etc/passwd 
and /etc/group for the composed docker image ?

(I can't help with skopeo, never used it before)
