--- Comment #4 from Mark Wielaard  ---
Aaron already wrote up a patch to use zero sized files as negative cache
instead of zero permission files:
https://sourceware.org/pipermail/elfutils-devel/2022q2/004861.html

The only question is how this works on upgrade with an old cache. But it might
just work out because the old negative cache files were also zero sized and the
unlink should just work despite any changes in permissions.

If someone could try it out and/or give it a formal review that would be great.

[PATCH] config: Add a versioned requires on libs for elfutils-debuginfod-client

[Mark Wielaard]

elfutils-debuginfod-client contains the debuginfod-client binary
which is uses libelf and libdw. Add an explicit versioned requires
on elfutils-libs so they will always be in sync like done with all
other inter sub package dependencies.
