Package: firejail
Version: 0.9.72-2
Severity: minor
X-Debbugs-Cc: smheidr...@weltenfunktion.de

Dear Maintainer,

Firejail's manpage says:

>The default Firejail filesystem is based on the host filesystem with the main
system directories mounted read-only. These directories are /etc, /var, /usr,
/bin, /sbin, /lib, /lib32, /libx32 and /lib64. Only /home and /tmp are
writable.

This list seems incomplete, because when I run `firejail` or `firejail
--private`, I can also read /dev, /opt, /media, /mnt, /proc, /run, /srv, and
/sys from within the sandbox.

I don't know if this is due to Debian-specific changes, so I'm raising it here
instead of upstream.
