Duplicate dependencies in util-linux

Duplicate dependencies in util-linux

When I run:  guix size util-linux | sort -n -k 3

I get:

store item                                                       total    self

This seems odd to me:

1. Why does it depend on two different version of ncurses6.0 ?
2. Why does it depend on both bash-4.4.0 and bash-static-4.4 ?

“guix graph -t references util-linux” explains this: libc depends on
‘bash-static’, and bash depends on an ncurses variant that is different
from that used by util-linux.

To fix the latter, we’d need to somehow declare a common ncurses package
to use to optimize our dependency graph.  Not sure how to do that.

HTH!
