OK, I've updated xenserver/etc_init.d_openvswitch to use the Debian LSB
headers now.

This is an issue that we have not considered at all before, because the
environments that we have encountered before all have /usr on a local
file system.  XenServer, for example, always has Dom0 installed on a
local disk.

I assume that the correct solution would be to install essential Open
vSwitch binaries in /bin or /sbin as appropriate?  We will need to think
about which ones are really important.

Since this is a new issue I'm going to consider the patch as updated to
be OK.  We can improve it later.
