Error: .asoundrc is a symbolic link pointing to a file outside home directory

[crocket]

~/.asoundrc is actually a symbolic link pointing to a file outside home directory.

Why does firejail refuse this?

Because of this issue, I can't execute librewolf and firefox with firejail.

I have lots of symbolic links that point to files outside home directory in home directory.

I found the answer in man firejail

--whitelist=dirname_or_filename

Whitelist directory or file. A temporary file system is mounted on the top directory, and the whitelisted files are mount-binded inside. Modifications to whitelisted files are persistent, everything else is discarded when the sandbox is closed. The top directory can be all directories in / (except /proc and /sys), /sys/module, /run/user/$UID, $HOME and all directories in /usr.

Symbolic link handling: with the exception of user home, both the link and the real file should be in the same top directory. For user home, both the link and the real file should be owned by the user.
