Sigh...

OTOH, in the mapping file I see:

   augeas:
     default: augeas
     deb: augeas-tools

This means that most probably there are different packages installed
depending on the distro:
- on Debian-based distros you get the command line tools
- on some distros (mostly RPM-based) you get only the shared library
- on some other distros (FreeBSD, and Linux distros not handled yet)
  you may get either everything, or the command line tools

OTOH², looking at the spec [1] makes me sad, as nothing really
depends on augeas-lenses, neither the shared library package nor the
tools package :-( This is totally nonsense, you install augeas in
openSUSE and it is broken by default if you have recommends disabled...

So my suggestion is to limit the manual lenses installation only on
openSUSE, as any other distro is already doing a sane job in this case.
