[linux-lvm] exit code of vgscan when everything is ok

[Arkadiusz Miskiewicz <arekm pld-linux org>]

Hi,

[root arm misiek]# rpm -q lvm2
lvm2-2.00.15-1
[root arm misiek]# /sbin/vgscan
  Reading all physical volumes.  This may take a while...
  No volume groups found
[root arm misiek]# echo $?
5

./lib/commands/errors.h:#define ECMD_FAILED             5

why it returns non-zero code? When there is no volume groups then it's normal 
to find zero of them and it's not failure.

This causes problems in init scripts.
