Thanks Felix for the report. IIRC, it was previously mounted and was supposed
to be converted to per-package hardlinks to parallelize sbuild instances and
ease debugging (by knowing later which exact snapshot was fed to a specific
build). We use small (1- / 2-TB) SSDs as job storage and a huge increase would
have been noticeable... We'll check.

With kind regards,
