The linuxdeploy utility makes it fairly easy to create AppImages -- self-contained, executable packages that are intended to run portably across GNU/Linux distributions. While Gridsync's existing PyInstaller-based packages are already highly portable in that they should run under any amd64 GNU/Linux desktop environment with glibc 2.17 or higher (which presently includes every popular modern distro that still receives security updates), the single-file, read-only AppImage format is conceptually simpler than a tarball full of binaries and leaves less room for user-confusion or error, particularly when updating to a new version of the application. Because of this, it would be useful if the Gridsync project could provide AppImage packages alongside or in place of the existing PyInstaller tarball distributions for the next release -- even if these AppImages merely contain the same files that would have been generated by PyInstaller itself.
