How does solaris 11 resolves hostname lookup and how is it different from solaris 10

Solaris 10 uses /etc/nsswitch.conf

Solaris 11 uses SMF service svc:/system/name-service/switch

e.g. to display current name resolution order

svcprop -p config/host system/name-service/switch

it generates the file /etc/nsswitch.conf (for backward compatibility ?)
