Given this command:

    $ apt rdepends --no-suggests --no-conflicts --no-enhances --no-replaces=
 resolvconf | grep -v '^    '
    resolvconf
    Reverse Depends:
      Recommends: resolvconf-admin
      Recommends: whereami
      Depends: netctl
      Recommends: rdnssd
      Recommends: debian-edu-config
      Recommends: education-common
      Recommends: ceni

It may be possible that it was installed transitively via rdnssd, which=20
is recommended by ifupdown-ng. I find it unlikely that LRob had any of=20
the others packaged installed on the system.

In any case, a command like `apt why resolvconf` may give a more helpful=20
answer than trying to figuring it out via rdepends.

Bye!
