Yann wouldn't have had this problem if he/she had *explicitly filled in all of
the fields* in each resource record, especially the owner name.  Whether the
owner name was fully-qualified is in fact irrelevant, and indeed using
non-fully-qualified domain names is a useful practice, especially when one
wants to do things like migrate to different domain names or compile multiple
"zones" from the same single source file.  The important factor here was the
omission of the fields, not whether those fields comprised fully-qualified
domain names.
