# 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.
