Bruce, i understand that we live in a broken and inconsistent world
with pollution, war, injustice all over the place. But I am just
trying to add a trivial feature to the version of bsdlabel in
FreeBSD-current in a way that does not upset the vast majority of
its user and does not require fixing the world's brokenness or using
"your version of disklabel". I understand your point and your
comments in this and other related threads, but other than as a
statement of principles it is difficult to make any practical use
of them, sorry!
cheers
