Variable weirdness ( was root not recognized )

[Sean Allen]

I figured out why the below didnt work for me.

I left out one key point about root /some/path;

We are actually doing:

set $root $base/public;
root $root;

because conf files are shared by multiple sites. this way each site  
set $base
and it gets reused in different places... to make the below work, with  
that
i need to change

>  if ( $site_maintenance )
>  {
>    root /maintenance/path;
>    rewrite (.*) /maintenance/index.html;
>  }

to

if ( $site_maintenance )
{
   set $root /maintenance/path;
   rewrite (.*) /maintenance/index.html
}

which is TOTALLY not how I expected variables to work.
is this documented somewhere?

that if you set root with a variable, to later change root you have
to change the value of the variable and that using root will have no  
effect?
