Comment 18 for bug 1862348

Thanks for the patch Alex, here is my review:

The title ("World writable lock file created in word writable location") for the lock file issue seems a bit inaccurate to me, I would rather use "World writable root owned lock file created in user controllable location", also there is typo in the second issue title, the "n" of between has gone away.

About the lock file fix, shouldn't we use a mode of 0o600 instead of 0o400 since os.open is called with the O_WRONLY flag? The lock file is not removed until reboot, it's fine for the first call when the file is created but it seems a bit confusing for the future calls don't you think?
