Well, I had a cursory glance dlz_bind9.c and also the bind9 source code I
could find (
and didn´t see any provision for 'reload' in there.
bind is clearly calling the dlz_destroy() function and not dlz_create(), as
one would expect, for a reload.
So yes, it appears to be a shortcoming of bind.
1) I suggest that the wiki for AD DC be updated to point out this fact.
logrotate scripts may use 'reload' which may be broken. a 'restart' is
better in that case.
2) I'll report this defect to the ISC.
