I tried to run fence with Claude Code and I got the following output:
$ fence -t code-relaxed -- claude
[fence:linux] runtime exec deny warning for /nix/store/d75200gb22v7p0703h5jrkgg8bqydk5q-coreutils-9.8/bin/coreutils (requested: chroot): shared binary also implements critical commands [cat head tail +30 more detected aliases, use --debug for expanded details], which will be collaterally blocked. To skip runtime blocking of "chroot" and silence this warning, add it to "acceptSharedBinaryCannotRuntimeDeny" in your command config.
