Module name: LVM2
Changes by: prajnoha at sourceware.org 2010-04-30 13:28:45
Modified files:
tools : lvmcmdline.c
Log message:
Don't run any complex initialisation for the "version" lvm2 command.
We can use it even in read-only environment where a try to initialise
file-based locking fails (not to mention other processing related with
lvm2 init). Simply, we want to output the version only, nothing else.
And this should always work.
