chown does not check for symlinks pointing to root when recursing through a tree

[jaggededgedjustice]

Even if the --preserve-root option is set the chown command will attempt to follow a symlink pointing to root. This can be seen with the following test:

mkdir point-to-root
ln -s / point-to-root/root
chown -RHh --preserve-root 1000 point-to-root/

The GNU chown will exit immediately, while this chown will follow the symlink and start trying to change root.
