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.

+.SH SYNOPSIS
+.nf
+hesinfo \fI[-bl]\fR \fIHesiodName\fR \fIHesiodNameType\fR
+.SH DESCRIPTION
+.I hesinfo
+takes two arguments, a name to be resolved and a string, known
+as a HesiodNameType.  It then prints the information returned by
+the Hesiod nameserver.
+.PP
+The value returned by
+.B hesinfo
+is of the type
+.I HesiodNameType.
+.PP
+.I hesinfo
+understands the following options:
+.TP
+.B -l
+Selects long format.
+.TP
+.B -b
+Prints the fully-qualified string passed to the nameserver.
+
+.PP
+.SS VALID Hesiod_Names
+The following types of identifiers may be used in the

+These values will be resolved by accessing the
+.B hesiod
+database.
+
+.TP
+.B \<username>
+the 8-character-or-less string used to identify users or classes
+(e.g. joeuser, root, 1.00, etc).
+Used with the
+.I Hesiod_Name_Types
+.BR passwd,
+.BR pobox,
+and
+.BR filsys.
+
+
+.TP
+.B \<uid>
+the id number assigned to a user.
+
+.TP
+.B \<groupid>
+the id number assigned to a group.
+
+.TP
+.B \<groupname>
+a name identifying a unique group.
+
+.TP 
+.B \<file-system-name>
+the name of an athena file system.
+
+.TP
+.B \<rvd server>:<pack>
+the name of an rvd's server and pack  seperated by a colon.
+
+.TP
+.B \<nfs server>:<partition>
+the name of an nfs server and its partition seperated by a colon.
+
+.TP
+.B \<workstation-name>
+the machine name of an Athena workstation (e.g. E40-343-3).
+
+.TP 
+.B \<service-name>
+name of an Athena service (e.g. Zephyr).
+
+.TP
+.B \<service-type>
+name of Unix service (valid entries are defined in /etc/services).
+
+.TP
+.B \<printer-name>
+name of a printer.
+
+.TP
+.B \<printer-cluster-name>
+name of an Athena print cluster.
+
+.TP
+.B \<foo>
+some
+.B hesinfo
+calls (e.g. 
+.B prclusterlist
+) do not require a specific
+.I HesiodName
+argument.  However, you must include a dummy string (e.g. 'foo') for
+.B hesinfo
+ to work properly.
+
+
+
+
+.PP
+.SS VALID Hesiod_Name_Types
+The following symbols are valid substitutions for the
+.I HesiodNameType
+argument to
+.B hesinfo.
+
+.TP
+.B \ passwd
+returns string suitable for inclusion in
+.I /etc/passwd,
+searching with
+.B <username>.
+
+.TP
+.B \ pobox
+returns information on the pobox assigned to the user specified by
+.I HesiodName,
+searching with
+.B <username>.
+
+
+.TP
+.B \ uid   
+returns string suitable for inclusion in
+.I /etc/passwd,
+searching with
+.B <uid>.

+.B - <file system name>, <username>, <rvd server>:<pack>, 
+.B and <nfs server>:<partition>
+
+.TP
+.B \ cluster
+returns information about the local cluster the workstation, specified by
+.B <workstation name>.
+Included is information about the local file and print servers.  This
+information is accesses by 
+.B clusterinfo 
+at boot time.
