I would actually agree. Having a part of the build system which
brings all the pieces together automatically for you would be good,
but it would be sensible for xen-unstable.hg to be less enthusiastic
about downloading stuff.
Perhaps we should more prominently advertise 'make install-xen
install-tools'. This should generally result in no downloads apart from
qemu, and that's a special-case dependency since it ties quite closely to
xen-unstable -- we can't just use any qemu tree. And of course you can
define XEN_EXTFILES_URL so as to make any download attempt fail, and then
you can go grab the packages yourself as you see fit and assemble your
requirements list. Imagine the noise on the mailing list if xen-unstable
didn't try to assemble itself automatically out of the box.
What about adding "make fetch-dependencies", and have the default build
say something like "X is missing. Type "make fetch-dependencies"."?
