Mount NFS share in /Volumes as a drive

I have spent quite a bit of time figuring out automounts of NFS shares in OS X...

Somewhere along the line, Apple decided allowing mounts directly into /Volumes should not be possible:

/etc/auto_master (see last line):

#
# Automounter master map
#
+auto_master        # Use directory service
/net            -hosts      -nobrowse,hidefromfinder,nosuid
/home           auto_home   -nobrowse,hidefromfinder
/Network/Servers    -fstab
/-          -static
/-          auto_nfs    -nobrowse,nosuid

/etc/auto_nfs (this is all one line):

/Volumes/my_mount    -fstype=nfs,noowners,nolockd,noresvport,hard,bg,intr,rw,tcp,nfc nfs://192.168.1.1:/exports/my_share

This will not work (anymore!) though it "should".

$ sudo automount -cv
...
automount: /Volumes/my_mount: mountpoint unavailable

What's the solution?

It's so easy my jaw dropped when I figured it out. Basically, we trick OS X into thinking we're mounting * somewhere else. *

When you're talking about paths in just about any environment, the root folder is the highest path you can reach, whether it's C:\ (windows) or / (*nix)

When you're at this path, attempting to reach the parent path, via .. will keep you at the root path.

For example: /../../../../ is still just /

By now, a few of you have already figured it out.

TL;DR / Solution:

Change your /etc/auto_nfs config from (this is all one line):

/Volumes/my_mount    -fstype=nfs,noowners,nolockd,noresvport,hard,bg,intr,rw,tcp,nfc nfs://192.168.1.1:/exports/my_share

To (this is all one line):

/../Volumes/my_mount    -fstype=nfs,noowners,nolockd,noresvport,hard,bg,intr,rw,tcp,nfc nfs://192.168.1.1:/exports/my_share

And re-run the automounter:

$ sudo automount -cv
...
automount: /Volumes/my_mount: mounted

..... there you go! Technically /../Volumes is still /Volumes, but the automounter does not see things that way ;)

This configuration persists the mount across restarts, and creates the mountpoint automatically.

I KNOW, RIGHT?
