blkdeactivate: check for lvm binary and skip LVM processing if not present
This removes dependency on lvm binary - if it's not present, all LVM processing is skipped (shouldn't normally happen because if lvm binary is missing then there's obviously nothing that would activate it, but let's make sure).
Without this tight dependency on lvm, the blkdeactivate script can be packaged with libdevmapper/dmsetup (in contrast to lvm as it was before) and as such the script can still be used to handle other DM devices. --- WHATS_NEW | 1 + scripts/blkdeactivate.sh.in | 24 +++++++++++++++++++++--- 2 files changed, 22 insertions(+), 3 deletions(-)
