Automounter
Modificar /etc/rc.config.d/nfsconf
NFS_CLIENT=1 NFS client functionality is required!
AUTOMOUNT=1 Start the automount deamon at boot time.
AUTO_MASTER=”/etc/auto_master” Choose a “master map” file.
AUTO_OPTIONS=”-f $AUTO_MASTER” Specify logging, timeout and other options.
AUTOFS=0 Disable AutoFS.
(si es AUTOFS, AUTOFS=1 y AUTOMOUNT=0)
# view /etc/auto_master
/net –hosts -soft Automatically soft mounts file systems under /net.
/home /etc/auto.home Refers automounter to the /etc/auto.home map.
/data /etc/auto.data Refers automounter to the /etc/auto.data map.
/tools /etc/auto.tools Refers automounter to the /etc/auto.tools map.
ejemplo /usr/export “-o vers=3,proto=udp” SERVIDOR:/nombredelexport
