# bsdlabel -e da0s1
. . .
Such that:

da0s1a => /
da1s1a => /tmp
da[0-3]s1b => swap
da[23]s1a, da[0-3]s1d, da[01]s1e => unused

# gstripe label -s 65536 var da0s1d da1s1d
Similarly for stripe/home, stripe/ports, and stripe/usr

# newfs -U /dev/stripe/var
. . .

ffwd a couple of months:

% bsdlabel stripe/var
bsdlabel: /dev/stripe/var: no valid label found

Oddly*, it all works perfectly.

My curiousity is about whether this is, not so much
expected, but proper** behaviour.  I have also done
gstripe the canonical way, with striping the daN or
daNsN, bsdlabel the stripe, newfs the resulting
partitions.  But doing it wrong way 'round seems
to do no (particular) harm.


* Or not-so-oddly, as you wish.
** Demure: "Trousers were meant for women, as women have
belatedly discovered." (Anthony Burgess)
