   Agreed, synchronizing updates and pulls would be too much of a
headache.

  But that would only need to be the case if the parent of the xen tree
contained xenbits.xensource.com/ext in the path (or some other locally
defined path if the parent is a local clone).  If we're building
xen-unstable.hg on ia64, it needs to pull linux-2.6.18-xen.hg just as it
would on x86.  This quickly starts to sound like rather complicated
rules.

   So far, this sounds like the best option.  This way it would work
just like the staging tree builds and would hopefully be less likely to
get broken.  We might also gain some flexibility in being able to create
new repos in the subdirectory.  Thanks,

        Alex
