I too now only have a single OS. So, I don't really need this feature
either. But, I do think we should offer an user experience as close as
possible to other distros. Hence, I think automatic os detection and
grub generation is worthwile. It's nice to have the grub work
automagically out of the box.

Also, I noticed that custom grub entries are a problem for the proposed
"guix system delete-generations"

Would automatic grub generation solve, or at least alleviate, this
problem?
