Yeah, especially since the lvcreate command is so complicated. Even
if there's only one thinpool in a VG, you have to specify it
explicitly:
lvcreate -V 5G --thinpool mythinpool -n thinlv lambda
Even though mythinpool is the only possible thinpool to use in VG
lambda, and even though it's clear that a thinLV is desired due to the
-V option, you still have to pass in the --thinpool option, and there
is no convenient short option character for it. :-(
Given that the devicemapper people are saying that thick snapshots are
legacy and deprecated, and everyone should be using the new coolness,
I'm pretty sure most users haven't gotten the message....
