Those files are the base used to compose the final scripts.

This commit nexedi/erp5@4e5e9a0f changed the behaviour of the Person.getTitle to fallback with Base.

This contains the code moved from slapos.package/playbook/role/install-script to provide installation scripts.

getJavascrip and getCss is overwritten under vifib_hosting_theme

The script SaleOrder_viewBreadcrumbWidget was disabled since begin of the project. So I remove all related code and clean up useless layout forms.

This code is used nowhere anymore.

Related tickets in this case also include all tickets related to the Hosting Subscriptions which are
allocated on this computer.

Not everything that is installed is registed into Software Release Module.

errors will be much more visible

Some testnodes were failing more or less randomly while calling "slapos node instance".
On failing nodes, unlike other ones, there was this unexpected log:

2016-10-06 15:35:18 slapos[11671] INFO Processing computer partitions...
2016-10-06 15:35:18 slapos[11671] INFO Launching supervisord with clean environment.

Then slapgrid was later failing with :

slapgrid_cp :   File "/opt/slapgrid/75e907b4c1523ecfa2aa210ec2754db4/eggs/supervisor-3.3.1-py2.7.egg/supervisor/xmlrpc.py", line 521, in connect
slapgrid_cp :     self.sock.connect(self.socketfile)
slapgrid_cp :   File "/opt/slapos/rebootstrap/parts/python2.7/lib/python2.7/socket.py", line 228, in meth
slapgrid_cp :     return getattr(self._sock,name)(*args)
slapgrid_cp : error: [Errno 2] No such file or directory

But the initial suspect logs sounds be the original issue that is the source
of next ones.

So it looks like supervisord was not able to start at all.

After playing with subprocess.Popen, is sounds not a good idea to play
with the keyword 'executable'. It looks like not always be strictly equivalent
to a replacement of the first argument of the first Popen args. It's much better
to directly set the process we want to call in the invocation list :
- it avoid to rely on a feature that is "very seldom needed" as we see
  in subprocess documentation
- it makes the code much readable, it avoid the guy reading the
  code wasting time understanding that the invocation_list is not
  really what is going to be executed.
