I agree with your first point about not *serving* files from /home. I 
disagree with your 'fix' in using /var.

Notwithstanding the anaconda installer's indications and instructions 
NOT TO, the installer always seems to WIPE the /var partition. 
Accordingly, you should use a symlink from /var/git (or in my case(s) 
/var/lib/mysql and /var/www/html) to somewhere else which will remain 
stable across a re-install.
In my case I point these instances to an actual "physical" partition 
which is /misc, which allows me to easily back-up all the active 
'stuff'. (It's really meta to describe a 'partition' on an SSD as 
'physical'... but there we are.)
Yes, it's a little more work on an actual re-install but I have some 
'run-once' script lines in /etc/rc.d/rc.local which handles all of the 
stuff I would not remember how to do, much less remember to do...

And Jeff, you should remember that it is spelt:
