Consider using sharun or userland-execve

Thanks @Samueru-sama for finding this.

sharun is just a binary that you symlink to inside the AppDir and based on the name of the symlink it will find the ld-*.so and call the binary in ./shared/bin while passing every single directory that contains libraries to --library-path when calling the ld-*.so. This means that when hardlinks get used /proc/self/exe is the name of the binary instead of ld-*.so, and since every single directory with libraries gets passed down with the --library-path flag there is no need to use patchelf to set rpaths.

Next step:
See whether we can use it in https://github.com/probonopd/alpine2appimage

https://zapps.app/technology/ "jumploader" seems to be doing a similar thing.

https://github.com/janispeyer/tinyshim is an implementation in assembly.
