My 'du' doesn't feature parameters "d1", I hope --max-depth is the same.
Additionally I've notice that there are several files larger than
100MB in "cache/0/00". Given their content, their first lines are most
probably from the upstream - which is fine - but should neither get
cached at all given max_size nor should the garbage (lots of ^@
following the first kilobytes) be there.
