o Text format now has a description and time field at the top level.
o archiving and backup set the description appropriately. eg,
for an archive:
description = "Created *before* executing 'lvextend test_vg/lvol0 -l +1'."
creation_time = 1013166332
for a backup:
description = "Created *after* executing 'lvextend test_vg/lvol0 -l +1'."
creation_time = 1013166332
This is preparing the way for a simple vgcfgundo command.
