Description Valeriy Malov 2019-10-17 15:07:57 UTC

Missing squashfs support in kernel results in mysterious error message from firejail when trying to run an appimage file:

Error mounting appimage: appimage.c:122 No such device

despite those appimages running fine on their own. This seems to be caused by use of squashfs:

https://github.com/netblue30/firejail/blob/04057a4652e889e23b66d95da770e7e7abf75ba5/src/firejail/appimage.c#L121

After rebuilding kernel with squashfs support, firejail runs appimages v2 just fine. This probably should be a kernel config check (CONFIG_SQUASHFS=y?) or a post-install note.

    sys-apps/firejail: Check for CONFIG_SQUASHFS
    
    firejail's --appimage mode requires squashfs. Not a fatal error since
    other modes work fine without it.
