Might as well take care of it with a v6, along with expanding the tests as you hint at below. > > + echo "This is currently unsupported by qemu-iotests" > > Is it just whitespace, or should we also be wary of other shell > metacharacters (such as quotes or glob characters)?

I know that '-' works, because for years my work directory has been called "qemu-kvm". I'm not sure about globbing characters like *, or quotes, but probably not a bad idea to exclude them as well (although, someone that uses '*' in their directory names is probably no stranger to data catastrophe!). > > > + exit 1 > > + ;; > > +esac > > + > > if [ ! -e "$TEST_DIR" ]; then > > mkdir "$TEST_DIR" > > fi > > > > -- > Eric Blake, Principal Software Engineer > Red Hat, Inc. +1-919-301-3266 > Virtualization: qemu.org | libvirt.org >

Currently, not all qemu-iotests work if TEST_DIR has spaces, and they also might not be safe. Refuse to run if TEST_DIR in this case, at least until all tests are fixed sometime in the future.
