Changelog for systemtap-headers-3.2-107.d_t.1.x86_64.rpm :
Fri Feb 16 13:00:00 2018 matzAATTsuse.com
- Add Conflicts with systemtap-sdt-devel, as that one again
provides the headers as well.

Thu Feb 8 13:00:00 2018 matzAATTsuse.com
- Created new specfile systemtap-headers.spec, so bootstrap cycles
packages can use them without blowing up the cycle.
