How can I use the /home directory on Mac OS X

NOTE: As of 2015, I no longer use or recommend this method. Instead I use Vagrant to setup virtual machines for dev and testing. It's free, relatively easy, and allows better matching of the production environment. It completely separates the development environment and you can make as many as you need. Highly recommended. I'm leaving the original answer below for posterity's sake.

I found an answer here on the Apple forums.

In order to reclaim the /home directory, edit the /etc/auto_master file and comment out (or remove) the line with /home in it. You'll need to reboot after this for the change to take effect (or, per nilbus' comment, try running sudo automount -vc). This works with Mac OS X 10.5 (Leopard). Your millage may vary for different versions, but it should be similar.

As noted on that forum post, you should also be aware that Time Machine automatically excludes the /home directory and does not back it up.

One note of warning, make sure to back up your /home directory manually before doing a system update. I believe one of the updates I did (from 10.6 to 10.7 for example) wiped out what I has stored in /home without warning. I'm not 100% sure that's what happened, but it's something to be on the lookout for.

Putting it all together from the tips and hints above:

• edit /etc/auto_master # comment out the line with /home in it.

• remount:

  sudo automount -vc

• make a softlink to the mac-ified dir:

  sudo ln -s $HOME /home/$USER

At that point, your paths should match-up to your production paths. env vars will still point to /Users/xxxx, but anything you hard-code in a path in your .bashrc --or say, in ~/.pip/pip.conf-- should be essentially equivalent. Worked for me.

re: "The real goal is to have all the files on the development Mac have the same filepath from the / root of the directory tree as the production server."

On production, my deploy work might happen in /opt/projects/projname, so I'll just make sure my account can write into /opt/projects and go from there. I'd start by doing something like this:

sudo mkdir /opt/projects sudo chown $USER /opt/projects mkdir /opt/projects/projname cd /opt/projects/projname

With LVM, I'll set a separate partition for /opt/, and write app data there instead of $HOME. Then, I can grow the /opt file system in cases where I need more disk space for a project (LVM is your friend.)

I tried it on Yosemite (OS X 10.10.1) the sudo automount -vc didn't work, I had to use sudo umount /home.

Therefore my workflow would be:

# comment out line starting with /home sudo vi "+g/^\/home/s/\//#\//" "+x" /etc/auto_master sudo umount /home # link actual home directory (/Users/<user>) to new 'home' (/home/<user>) ln -s $HOME /home/$USER
