I just wanted to briefly mention that if you use the "declarative
approach" to specifying user profiles, via the --manifest option to
"guix package", you will avoid this problem entirely.  I've been happily
using that approach for years, and I literally cannot remember the last
time I saw a "conflicting entries" message.  I heartily recommend it.
