Quirks

WARNINGS

• NEVER run strip, objcopy or any other binary rewriting tool as they will often just strip the squashfs|dwarfs archive, only preserving the runtime.

• A typical .appimage file is not a real elf binary, thus will not survive this process.

• On NixOS, you will need to follow: https://wiki.nixos.org/wiki/Appimage
