OK, so parts of the news item are not to be taken literally, and other |
21 |
parts are. Perhaps it would be wise to mark the sections so we can |
22 |
tell the difference? ;) |

It's entirely possible for udev (or any other program) to check |
29 |
whether a file is empty or not and behave differently depending on |
30 |
that test. And if it is explicitly stated that something depends on a |
31 |
file being "empty", that's what I assume was indended. Of course it's |
32 |
possible to determine via experimentation that "nothing but comments" |
33 |
produces the same behavior as "empty". Of course we all figured that |
34 |
out after we realized that udev wasn't behaving as was described in |
35 |
the news entry and started reading other documentation. |
