Why? "Permission denied"

Firejail related?

The AppImage runs just fine on my local machine without Firejail.

firejail ./DeviceInterface-x86_64.AppImage �/bin/bash: /run/firejail/appimage/.appimage-7979/AppRun: Permission denied

May be caused by Firejail? #456 (comment)

I'm pretty sure this happens when the AppImage unmounts itself before the next command can run. The only solution I've really found for this is to move the component that is being called out of the AppImage temporarily and call it from the directory I've moved it to. I've tried adding sleeps and such, but no dice.

For example, with ROSA ImageWriter, it needs to be ran as root with something like xdg-su. xdg-su will run fine, but the AppImage seems to unmounts itself as soon as xdg-su finishes running unless I move the RosaImageWriter executable outside of the AppImage and call it from there.

Many apps have this "permission denied" thing:

Why?

Seems to be related to Firejail. E.g., #1025 (comment) shows how to verify this.
