An increasing version and/or release number helps to update existing
packages without --force as in "rpm Uvh --force xen.rpm". Instead its
possible to do "rpm -Fvh *.rpm" to update only already installed
packages.
The usage of --force disables essentials checks such as file conflict
detection. As a result the new xen.rpm may overwrite files owned by
other packages.
With the current way of calculating version-release it is difficult to
get an increasing release number into the spec file. The release is
always zero unless "make make XEN_VENDORVERSION=`date +.%s`" is used,
which has the bad side effect that xen.gz always gets a different
filename every time.
Update mkrpm to recognize PKG_RELEASE=. Its value will be appended to
the Release string. It can be filled with a time stamp, like:
make rpmball PKG_RELEASE="`date +%Y%m%d%H%M%S`"

Even if xen is configured and compiled with different --prefix= so that
it operates entirely below $prefix, the resulting package from 'make
rpmball' is always called "xen.rpm".
Use an environment name to give a different name.
This can be used like this:
suffix=-bugN
prefix=/opx/xen/staging${suffix}
./configure --prefix=${prefix}
make rpmball PKG_SUFFIX=${suffix}
The result will be "xen-bugN.rpm" instead of "xen.rpm". The benefit is that
many xen${suffix}.rpm packages can be installed at the same time.
