It is not supposed to be possible for even UID 0 to write on a directory,
EXCEPT via access to the "raw device".  If the apparent '/' has the high
bit set, then you already received an answer.  If not, then you'll have
to ALSO access the "raw device" -- basically you need to "zap" the entry
using fsdb or equivalent, then get fsck to fix up the filesystem.
