OK, I've been trying various ways of doing this, with no success. It looks
like the best chance is with "disklabel -R wd0 [protofile]" which would
write an in-core disklabel, but I haven't been able to get it to work
successfully. I get an error telling me I should use the -r flag as well;
but if I do this, doesn't this clobber the os-bs 2.0 boot record?
I've been editing the output of "disklabel wd0" (included below), but am
not sure what the correct things to change/add are... can anyone help me?
I have read the man page, really I have, but it's just not enlightening
enough... help?
Thanks much,
Eric
