This is precisely the reason why the parity rewrite has been
moved. There is no good reason to start the parity rewrite sooner;
it would only drastically slow down fsck and other bootup operation.

You SHOULD NOT use 'c' or 'd' parts of the disk. 'c' is reserved
for 'NetBSD part of the disk' and 'd' for 'whole disk' (on i386).
Create a separate disk part, can use one of a,b,e-p for this.

Broken setup.
