$VH_ROOT not work properly at server level
At the server level, I added the following entry into the Apache-style settings:
php_value open_basedir "$VH_ROOT/public:$VH_ROOT/includes"
The resulting open_basedir value though held the server's prefix not the $VH_ROOT. If I add this entry at the template level, it works as expected - not tested on the individual host level, but I'm assuming it works correctly there.
I've not tested any other uses of $VH_ROOT at the server level.
I'm guessing this isn't the intended usage.
