Yes, I gree that the README should tell the user to set TOOLSTACK=xapi
if he or she wants to enable xapi.

No, xapi cannot cope with xend running at the same time. It can cope
with xl being used, as long as xl is not used to change the state of
VMs which xapi is managing.
What I am saying is that someone might want to switch to using xl
instead of xapi. Making the change you suggested xcp-xapi.init would
then mean that setting TOOLSTACK=xl would cause an error, when in fact
it is a perfectly valid thing to do.

Agreed, let's make sure to add the TOOLSTACK=xapi setting to the
README before Wheezy.
