Description
mkdir rod
cd rod
truncate -s 1M file
chmod a-w .
uu_shred -u file
test -s file && echo still allocated
I.e. shred should ftruncate() rather than relying on unlink()

Research direction
Start with the Rust implementation of the shred command and reproduce the provided mkdir, chmod, truncate, and uu_shred -u sequence. Trace how the -u option handles the file, then verify that the file is deallocated even when the containing directory is not writable and that the example no longer prints “still allocated”.
