base-files postinst recurses into /etc/udev/.dev while trying to fix permissions

Binary package hint: base-files

While upgrading base-files to the latest version on hardy, the postinst, to fixes permissions in /dev, recurses into /etc/udev/.dev, and then into /proc and other parts of the filesystem while following symlinks in /dev. This gives out a copious amount of output, looking like this:

It would be nice to exclude this path from the find invocation...
