Version 2.02.105 -
=====================================
+ Add allocation/wipe_signatures_on_new_logical_volumes_when_zeroing to lvm.conf.
Do not fail the whole autoactivation if the VG refresh done before fails.
Do not connect to lvmetad on vg/lvchange --sysinit -aay and socket absent.
Use lv_check_not_in_use() when testing device in use before merging.
