I'd like to be able to add something like this to a kickstart:

logvol /foo --vgname=dat --name=mystripe --size=10000 --fstype=ext3 \
  --stripes=3 --stripesize=128 --onpv=pv.1,pv.3,pv.4

Of course there could be a default stripesize. And probaby the physical volumes
too, by using lvm default of drawing from whatever was put in the volgroup.

But certainly some sanity checks are needed to ensure that the number of stripes
is appropriate for the physical volumes available or selected.
