SELinux dependency for Linux AppImage

[tlonic]

I'm trying to run the AppImage of Praaline on ArchLinux, but it says it needs libselinux. SELinux is not officially supported in ArchLinux.

Steps to reproduce:

1. Download https://www.praaline.org/downloads/Praaline_0.9.0410_Linux_x86_64.AppImage
2. chmod +x Praaline*.AppImage
3. ./Praaline*.AppImage

Receive the following error: ./Praaline_0.9.0410_Linux_x86_64.AppImage: error while loading shared libraries: libselinux.so.1: cannot open shared object file: No such file or directory

It seems like this is an issue with other AppImages, see here -- is the SELinux dependency necessary here?
