<p dir="ltr">Here's a possibly stupid question, indulge me....</p>
<p dir="ltr">Seems like we're always going to need a simple (ish) tool that just installs the openstack services on a single machine, without any need for VMs.</p>
<p dir="ltr">In fact, the tripleo installer - instack - is one such tool. Packstack is another, more flexible such tool. Should we consider merging or adapting them to be the same tool?</p>
