Ugg. That's because _qemu_io_wrapper is a shell function, but sudo can't
directly invoke shell functions.
It passes on systems where $sudo expands to '' because the test is being
run as root.
I think that test will have to be rewritten to use raw invocation
(untested):
$sudo "$QEMU_IO_PROG" $QEMU_IO_OPTIONS --format "$IMGFMT" --nocache -c
"read 0 65536" "$TEST_IMG" > out 2> err
and then manually feed "out" through _filter_qemu_io and replay "err"
(since you can no longer take advantage of the '(subshell)|pipeline'
trick added by 934659c to force bash to display core dumps).
