ovirt-imagio does not invoke any external program.

Vdsm tests invoke virt-alignment-scan but not in a way that can leave
anything around:

LIBGUESTFS_BACKEND=direct virt-alignment-scan --help
LIBGUESTFS_BACKEND=direct virt-alignment-scan --add no-such-file

I don't know about other tests using libguestfs.

But how a program running inside mock chroot can access host's /var/tmp?
