Available only on Sun 386i systems running a SunOS 4.0.x release or earlier. Not a SunOS 4.1 release feature.
auto.home resides in the /etc directory, and contains automount.8 map entries for user's home directories. On Sun386i systems, this file is used to build the auto.home Network Information Service (NIS) map used by automount at system startup and reads the auto.master NIS database, which contains an entry for auto.home and /home . The auto.home map contains entries for each username in the NIS passwd map, and the hostname:/directory to NFS mount.
References to /home/username are translated by the automount daemon using the auto.home map, and the directory specified in the map entry is nfs mounted and that directory returned to the user's program.
User accounts created using snap.1 or logintool.8 have passwd.5 entries where the initial (home) directory name is, in the form /home/username. snap and logintool also automatically create the auto.home entry for a user account. The format of the entry is described in automount.8 An example entry is:
mtravis system2:/export/home/users/mtravis
Thus, when the user mtravis logs into a Sun386i systems, the automounter automatically mounts his home directory from system2. This allows a user to log in to any Sun386i workstation on the network and be automatically placed in their home directory.
The convention for the format of home directory names used by snap and logintool is:
/export/home/groupname/username
Note: this is a different map and mechanism for home directories than the one that the automount daemon provides with the -homes switch. This is because the Sun386i convention for the format of home directory names differs and provides directories that can be used as mount points on a per user and per group basis.
The Network Information Service (NIS) was formerly known as Sun Yellow Pages (YP). The functionality of the two remains the same; only the name has changed.
