Bug ID: 1180882 Summary: perf does not build reproducibly Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: All Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: bwiedemann@suse.com QA Contact: qa-bugs@suse.de Blocks: 1041090 Found By: Development Blocker: ---

While working on reproducible builds for SLE and openSUSE, I found that our perf package differs across builds.

/usr/bin/perf differs in ELF section .dynsym /usr/bin/perf differs in ELF section .rela.dyn
