You can run windows programs from the literal dark ages on Windows 11 Enterprise.

In government at least this is a big deal. Will binaries from 15 years ago run on SUSE Linux? Somehow I doubt it.

I've seen hardware utilities that look like pre Windows 95 programs running on modern windows? Is that sound possible?

Linux kernel API is stable. Why wouldn’t you able to run properly written program from 2009? I’m pretty sure it’ll run just fine.

glibc on the other hand is very much not.

[vbezhenar]

glibc is backwards-compatible as well.

Until it isn't. https://github.com/ValveSoftware/Proton/issues/6051

No glibc will not fix it and the rolling release distros are now patching their libc.

Here is the list of ABI breaking changes:

Also a system layer isn't just the C library. Other core Linux libraries often break their ABI too.

If it is important enough, the government should demand ownership of the source code, not just take some binary and call it a day.
