Add nsswitch support. By creating an /etc/nsswitch.conf file, you can

configure FreeBSD so that various databases such as passwd and group can be
looked up using flat files, NIS, or Hesiod.

= Hesiod has been added to libc (see hesiod(3)).

= A library routine for parsing nsswitch.conf and invoking callback
  functions as specified has been added to libc (see nsdispatch(3)).

= The following C library functions have been modified to use nsdispatch:
    . getgrent, getgrnam, getgrgid
    . getpwent, getpwnam, getpwuid
    . getusershell
    . getaddrinfo
    . gethostbyname, gethostbyname2, gethostbyaddr
    . getnetbyname, getnetbyaddr
    . getipnodebyname, getipnodebyaddr, getnodebyname, getnodebyaddr

= host.conf has been removed from src/etc.  rc.network has been modified
  to warn that host.conf is no longer used at boot time.  In addition, if
  there is a host.conf but no nsswitch.conf, the latter is created at boot
  time from the former.
