Okay, I think that the problem is that we forgot to call xapi with the
-onsystemboot flag in the xcp-xapi.init script. Here is an untested
patch that you should be able to manually apply (as in edit the init
file by hand) to test if this fixes the issue.

I'll push a proper patch to my github soon.
