[lvm-devel] patch3/4



3) lvm.8.reordering+pvcreate.patch
It seems that right now, neither built-in commands nor commands are
ordered
alphabetically.
The patch orders them in a (IMHO) better way, especially:
First VG-, then PV-, then LV-, then "general"-commands.
In each section I also made some grouping, e.g. commands that do display
stuff,
create/remove/rename, resize/extend, etc.
Please check, that (when copy&pasting around) I did not accidentally
drop one ;)

Another thing done by the patch: For pvcreate it's hinted (by "etc")
that not
only disks and partitions can serve as PV. (e.g. md devices, or
dm-crypt, etc.)
