Hm, interesting. What problems do I have to expect? I am asking because
the basics seem to work fine so far with just a few adjustments to the
provisioner barclamp e.g. to have it generate the appropriate pxe config
for SUSE and to provide a SUSE specific crowbar_join script.
There are of course still some manual steps involved to setup the admin
node (like copying the install source to the appropriate directory).
Also note, that this is just meant as a temporary workaround until we
have the admin node stuff working on SUSE.

The thing is that we already have quite some tools and products that
handle exactly these kind of problems (building packages taking care of
the dependencies and distributing updates). Ideally we would integrate
with these tools to distribute updates to the Crowbar Cluster. But this
is still to be discussed and nothing is set in stone yet. Currently I
mainly did it this way because it got me much faster to a state where I
could actually deploy something SLES based with Crowbar.
