“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!
