I really doubt a X11 Flatpak from today will run in Fedora from 10 years time, much less 20 years time. They will break XWayland (in the name of "security") much before that. They will break D-Bus much before that. In addition, the kernel breaks ABI all the time; sometimes this is partially workarounded thanks to dynamic linking (e.g. OSS and solutions like aoss). Other times not so much. I feel that everytime someone introduces a "future proof" solution for 20 years they should make the effort to run 20 year old binaries on their Linux system of today and extrapolate from it.

As someone who actually has run at-least-15-year-old binaries (though admittedly not x11 ones for my use case), I can strongly state the following advice: * do not use static linking for libc, and probably not for other libraries either C-level ABI is not the only interface between parts of a program. There are also other things like e.g. well-known filepaths, and the format of those can change. A statically-linked program has no way to work across a break, whereas a dynamically-linked one (many important libraries have not broken SOVERSION in all that time) will know how to deal with the actual modern system layout. During my tests, all the statically-linked programs I tried from that era crashed immediately. All the dynamically-linked ones worked with no trouble.

The kernel breaks ABI? Since when?
