Sparcs have a known issue with the `wc' command, see
  http://cdimage.debian.org/~costar/pseudo-image-kit/
(at the bottom).

Also, if (many) other processes are running, things may slow down quite much.
This is because make-pseudo-image is a shell script which calls many external
programs, and each call gives priority to other running programs (even if the
called program would terminate immediately).

Hmm, in that case setting up a simple FTP/HTTP/rsync redir to e.g.
ftp.sunet.se would be faster than using your own disks for the mirroring,
wouldn't it? ;-)
