You can't just re-interpret standards to match a context you know very =

isn't applicable and consequently redefine what the word "device" means.
You're on a slippery slope and while you may not see it as a problem, =

do make it a problem for FreeBSD users. It's our users we should be =

in mind when we solve problems.

Right. Another happy user that sees his/her FreeBSD installation =
destroyed
or degraded (no mirroring, warning messages about corrupted GPT, etc) =
for
no apparent reason and without any kind of warning that what he/she is =
doing
is potentially harmful... That's the spirit!
