# Veriying avoiding installing over an active local storage,
# we use the following 'find' options:
#   -xdev, Don't descend directories on other filesystems, those are not considered local storages,
#          and are not affected by the installation
#   -not -empty, Skip empty metadata files as storage domains cannot have empty metadata file.
# we also exclude folders starting with /rhvh which holds symbolic links to block storage domains
# Or mounted file based storage domains, although these are likely skipped by -xdev.
