Comment 9 for bug 1793056

Sorry, had a typo in my post above...I appended (>>), I didn't overwrite (>).

However, point taken about creating a new file. I've done that and is working. Thanks.

For anyone coming from google, the temp solution on Ubuntu 18.04 is:

# echo dash > /usr/lib/x86_64-linux-gnu/guestfs/supermin.d/zz-lp-1793056

(Just remember to clean up zz-lp-1793056 once the problem is fixed in future package release).
