broken mountpoint can remain #22
Description
There was a report at Eden from an user that could reliably cause the Eden.AppImage to fail with Illegal instruction (core dumped).
Step to reproduce:
- Have Eden running in the Steamdeck and then force close it by switch to desktop mode.
What's interesting is that if the user downloads another AppImage that uses uruntime, and renames it to have same name as the Eden AppImage, that other appimage is also broken.
Rebooting the system fixes the issue. So this looks like some stale mount issue??
Here is the strace output:
