dh_installnss - enable NSS services

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

Example

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
