Hi,

I've built a very generic Apache role that can set up a bunch of vhosts, 
however I'm running into a design problem.

Each vhost has a dependency, for example 'subversion' requires a bunch of 
packages and a repository to be created (subversion specific tasks), the 
same goes for all the other vhosts.
Running the 'apache' role and passing in my vhosts structure will set up 
the vhosts but not the dependencies, so I was trying to reverse the 
behavior i.e. setting up subversion will setup apache through a role 
dependency which works fine, the only downside is that certain tasks in the 
apache role get executed over and over again even though I just want to add 
a 'vhost' at that point.

Options I see:

1. Create a separate role 'apache-vhosts' to take care of setting up vhosts
2. Pass in a list of all vhosts to the apache role at once after setting up 
all "dependencies"

Point 2 seems the most elegant to me, however then I run into the problem 
of "collecting" the variables of all these roles.
I'm clearly struggling with this, does anybody have some design advice on 
how best to approach this? 

Just to make it clear, I do want the roles to "know" about each other, 
running apache with "setup these vhosts" and then running the roles to 
setup the content seems a bit silly to me, as those content roles could set 
the document root (install dir) etc. etc.

Thanks guys.

Nico
