NAME

       dh_installnss - enable NSS services

SYNOPSIS

       dh_installnss [debhelper options]

DESCRIPTION

       dh_installnss is a debhelper program that is responsible for injecting NSS (Name Service
       Switch) services into /etc/nsswitch.conf.

FILES

       debian/package.nss
           Lists the services to inject into /etc/nsswitch.conf when a package is configured and
           to remove when a package is removed or purged.

           Each line in that file should be of the form

           "db position service action condition"

           where the fields contain the following pieces of information:

           "db": the NSS database in which the service will be added. Usually "hosts".
           "position": where to add the NSS service.
               Possible values are "first", "last", "before=service", "after=service", plus the
               pseudo-positions "remove-only" and "database".

               The pseudo-position "remove-only" is used to mark services that are not going to
               be added during the installation of the package, but that will be removed during
               its removal (e.g., legacy services).

               The pseudo-position "database" is used to request the addition of a non-standard
               NSS database. When "database" is used, all other fields should be left empty.

           "service": the name of the NSS service to add.
           "action": optional action specification "[STATE=ACTION]".
           "condition": optional set of conditions to better define when a service should (or
           should not) be installed. Only one kind of condition is currently defined:
           "skip-if-present=service,service,...".

           Additionally, text between a "#" character and the end of line is ignored.

EXAMPLES

       An example debian/nss file could look like this:

           hosts before=dns mdns4
           hosts before=mdns4 mdns4_minimal [NOTFOUND=return]
           hosts remove-only mdns    # In case the user manually added it

       After the installation of this package, the original configuration of the hosts database
       in /etc/nsswitch.conf will change from:

           hosts:    files dns

       to:

           hosts:    files mdns4_minimal [NOTFOUND=return] mdns4 dns
