This is from cap-std which would error out on absolute symlinks
cap-std refuses to follow absolute symlinks since they would escape the sandbox, returning PermissionDenied. When /etc/containers/policy.json is a symlink to e.g. /usr/share/containers/policy.json, this caused policy resolution to silently skip the file. Switch to `cap_std_ext::RootDir` that handles the above semantics by itself Test written by Claude Fixes: bootc-dev#2339 Signed-off-by: Pragyan Poudyal <pragyanpoudyal41999@gmail.com>
