Do you want me to use the production (Lenny) installer? Or do you want
me to use the "daily build" from Squeeze to do the installs?

After installing parted (Version 1.8.8.git.2008.03.24-11.1, remember this
is a production Lenny system) I now get:
odocdeb1:~# parted /dev/dasdb print
Error: /dev/dasdb: unrecognised disk label
For a CMS-format disk on an ECKD device, the first two physical blocks
are IPL records. The third physical block (cylinder 0, head 0, record 3)
is the CMS disk label, whose exact
format I can supply if you need it. (On an FBA DASD, the second
block is the disk label. That's physical block 1, counting from 0.)
The first four bytes of the label are "CMS1" in EBCDIC, which is
X'C3D4E2F1' The next six bytes are the volume serial number in EBCDIC.
For example, if the volser is "DEB200", that would be X'C4C5C2F2F0F0'.
The other fields I can get for you if you need it.
