Sample unsorted gstat output

Modern(ish) LSI controllers (and perhaps others) probe and report devices i=
n a
random order which may change after a reboot. This pretty much makes glabel
mandatory for referring to devices. LSI says that's the just way it is, and=
 to
use either operating system labels or create RAID volumes on the controller.

gstat reports devices based on their hardware device names, so there is a n=
ice
pre-sorted (in some kernel ordering) list of devices. For example, da0 thro=
ugh
da16 are displayed in order. So far, so good.

If I glabel the devices as slotN and then do "gstat -f slot", I get a list
which is still sorted by the hardware device name as shown in the attachmen=
t,
even though the more useful order would be the slotN names I assigned. I
propose a -s flag which would sort the display by the name.
