```

Is there any way to optimize that? Like creating an scm to install actual files 
instead of an AppImage to avoid fuse hassle, or running it without emulating 
FHS to get access to system `grep coreutils gcc-toolchain gtk+ alsa-lib`, or 
using per default WayLand to avoid all the x11 hassle, or lighter packages than 
`grep coreutils gcc-toolchain gtk+ alsa-lib`, or to make work fuse to avoid 
extraction
