Oh, hmm, good point.

Perhaps =E2=80=98essential-services=E2=80=99 could check whether
=E2=80=98hosts-database-service-type=E2=80=99 is part of the
=E2=80=98operating-system-user-services=E2=80=99.

If it is, it would extend it; if not, it would do nothing.

=E2=80=98hosts-database-service-type=E2=80=99 would be part of =E2=80=98%ba=
se-services=E2=80=99, but
in the container-with-shared-network case, we=E2=80=99d remove it (in a
procedure similar to =E2=80=98virtualized-operating-system=E2=80=99.)

How does that sound?

Thanks,
Ludo=E2=80=99.
