It might make sense as well to move the info.dir file from base-files
to whatever new package install-info ends up to (CCed Santiago, as I

We can drop cleanup-info as well (just emitting warnings for now) as
we'll have update-info-dir.

I'm not sure if crippling install-info is a good idea, upstream
projects should be able to use it. Also non-transitioned packages
should be able to install their info files and make those be added
to the dir file. The dir file is going to be regenerated eventually
anyway, so no much problem with broken dir files anymore (or less than

I think Recommends might be too strong, Suggests could be better. Also
packages with man pages do not Suggest/Recommend man-db, but there
should be many more having man pages than info files, so it seems

If install-info keeps working there's no actual need for this, and
makes life of backporters easier, packages will get this eventually.

This last step could probably be moved after the debhelper upload, so
that fast maintainers might just fix their stuff before needing to
