However, at least for *Enterprise Linux 8, it seems a lot of packages were built assuming the distro's default Python 3.6, but at runtime only invoke "Python 3", not 3.6 specifically. It seems that I still need Python 3.6 for most packages installed via DNF on EL8, but I also definitely need Python 3.8+ for multiple packages I use installed with PIP. So, the workaround to having both installed on my system at the same time would be to edit the shebangs to include the minor version of Python that each application requires. ...Right? I wanted a sanity check before I bother sending spam to EPEL package maintainers. Or, is this even a reasonable thing to ask package maintainers to change, or should I just start patching the local shebangs myself? Or is there a better solution?RHEL 8 has brp-mangle-shebangs, and when correctly invoked (which EPEL should do already), the interpreter path is already rewritten for you. My packages in EPEL 8 seem to have this, at least.
Yeah, this should get done automatically, but on my system at least there are some files in /usr/bin without the minor version:
