System administrators can use a new variable, NATISA, which corresponds to the output of the isainfo -n command, in automounter maps. You can set this variable to allow different parts of a directory hierarchy to be mounted on the system depending on whether the system supports 32-bit or 64-bit native applications.
For example, the following map entry allows a client to mount either /export/sparc/bin or /export/sparcv9/bin depending on whether 64-bit applications are supported on that system.
/export/bin server:/export/$NATISA/bin -ro |
See automount(1m) for more information.
