There was a problem hiding this comment.
Even if we don't fail it appears that the GNU implementation provides a warning:
sudo unshare --mount sh -c 'mount -t tmpfs none /proc; stat --format="%m" /tmp'
I'm getting: "stat: cannot read table of mounted file systems: No such file or directory"
Only read mount information when needed (%m directive) and handle gracefully when /proc/self/mountinfo is not accessible, fixing stat failures in chroot environments without /proc mounted. see https://bugs.launchpad.net/ubuntu/+source/rust-coreutils/+bug/2133797
