Error: Transaction test error:
  file /usr/bin from install of s2-20240306-1.x86_64 conflicts with file from package filesystem-3.16-2.el9.x86_64

Cause:

The package should not declare system directories itself. This has been in the RPM spec for years but only in the recent versions of RPM is it enforced.
