The /etc/auto * files
From OS X Scientific Computing

Using the /etc/auto_* files for automounting NFS filesystems in OS X 10.5.
This is new and sufficiently different that it took a while, and help from Apple, to figure it out.
man auto_master
to get the official skinny.
Create a directory as a mount point wherever suits you, eg:
sudo mkdir -p /my_mountpoint
Create a file /etc/auto_my_mountpoint
You can call it auto_anything , but this helps keep it simple
Put lines like the following in that file
# # Automounter map for /my_mountpoint # +auto_my_mountpoint # Use directory service Users my.other.computer:/Users Drive1 my.other.computer:/Volumes/AnotherPartition Drive2 my.other.computer:/Volumes/YetAnotherPartition
Edit the file /etc/auto_master
Add a line such as
/my_mountpoint auto_my_mountpoint -nobrowse
Restart the automounter
sudo automount -vc
Test it
cd /my_mountpoint/Users
It should now automount, and you should see this when you issue the commands
df | grep my_mountpoint
map auto_my_mountpoint 0 0 0 100% /my_mountpoint my.other.computer:/Users 241232080 175237776 65482304 73% /my_mountpoint/Users
Note that there is no need to have an /etc/fstab entry in this case. The other partitions mount automatically when you cd into them.
Tweak for non-OS X filesystems
The good folks at Apple suggested I do the following to make automounts work for my linux and sun filesystems:
Change
AUTOMOUNTD_MNTOPTS=nosuid,nodev
in /etc/autofs.conf to
AUTOMOUNTD_MNTOPTS=nosuid,nodev,resvport
Back to NFS on OS X 10.5
