MacOS X 10.5 (Leopard) Automounter

Operating System:  MacOS X 10.5, Leopard
First version:     08.11.2007 by Marc Petitmermet
Last modification: 27.12.2007 by Marc Petitmermet, added missing "-P" option and /etc/autofs.conf settings

Works like in Solaris! Add "resvport" for using reserved ports. The necessary settings can be either set individually for each automount point in /etc/auto_master or generally in /etc/autofs.conf.

%> cat /etc/auto_master

# Automounter master map

/net            -hosts       -nobrowse,nosuid,resvport
/home           auto_home    -nobrowse,resvport,-P,intr
/Network/Servers             -fstab
/-              -static

%> cat /etc/autofs.conf
[snip]
# Mount options.
# A string containing a comma-separated list of mount options
# that will be applied, by default, to all mounts done by automountd(8).
# The options for a particular mount can override these options.
# This controls the same default mount options that the -o option to
# automountd(8) controls.
