First, you sent this to "linux-raid-owner" instead of just
"linux-raid".  The former goes to me, not to the mailing list.

I've corrected it in the CC:

Second, to answer your question, for some disk label variants you
risk over-writing the disk label if you use the whole device
as part of your RAID volume.  This definitely will happen, for
example, with Sun disk labels.
