Hi Arun,

Oh, hmm, good point.

Perhaps ‘essential-services’ could check whether
‘hosts-database-service-type’ is part of the
‘operating-system-user-services’.

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

‘hosts-database-service-type’ would be part of ‘%base-services’, but
in the container-with-shared-network case, we’d remove it (in a
procedure similar to ‘virtualized-operating-system’.)

How does that sound?

Thanks,
Ludo’.
