On some systems, /usr/local and /opt/sfw are automounted from a central server. This is sometimes handy in a lab environment, but at other times it really makes things difficult.

Fortunately, it's easy to turn off. All you have to do is add a couple of lines to your /etc/auto_master file and stop/start the automounter service.

Here's an example of an auto_master file with automounting turned off for /usr/local and /opt/sfw:

# Master map for automounter
#
/usr/local      -null
/opt/sfw        -null
+auto_master
/net            -hosts          -nosuid,nobrowse
/home           auto_home       -nobrowse
/xfn            -xfn

After you edit the file to add the two lines, stop/start the automounter like this:

/etc/rc2.d/S74autofs stop
/etc/rc2.d/S74autofs start

Ta-da!
