Currently the %post scriptlet of the kernel creates /boot/do_purge_kernels to
trigger zypper's kernel purging.

Could this be modified so that it only creates this file on upgrades and *not*
on fresh installations? Currently this will cause zypper to try to purge old
kernels on fresh installations. While that is short, it can cause noticeable
delays until zypper can be used again, especially in resource constrained
systems.

Could the creation of this file be adjusted so that it is only created on
upgrades and not on new installations?
