> This is untrue. You can run old Linux binaries on modern Linux systems if you have the older libraries. Again, 0.01% of people in the world could do it, 0.0001% would do it. That's all you need to know about Linux compatibility. And don't get me started on LD_LIBRARY_PATH not working for glibc but you conveniently "forgot" about that. Compatibility "exists" except when it doesn't and it's extremely hard to achieve…
Use the other system’s elf interpreter (which is conveniently a library). Then it should work. Saying an ability to run older binaries does not exist is just wrong. By the way, when someone makes an assertion that something is always true, it only takes 1 counter example to disprove it. The assertion that you cannot run old Linux binaries on a newer system has been disproven by a counter example.
For 99.99% of users this "ability" does not exist. End of story. Period.
I don't care about hacks on tops of tricks on top of hacks. People are not interested in this madness.
Every second comment in this discussion comes from a hardcore software developer who desperately tries to vindicate core Linux flaws by providing workarounds which would work only for people like you.
This is NOT how the world works. This is NOT what people care about or interested in. If cars, refrigerators, microwave ovens worked like that no one would buy them.
If it's Linux? Ah, totally fine.
I'm done with this exercise in futility.
