thanks for providing this updated document. With regret, I have to raise one issue:

The final sentence

	Once an initial rollover has taken place, the RZERC suggests that future
	rollovers be done at predefined regular intervals in order to minimise the
	risks arising from static configurations that may harm future changes to the root KSK

This issue is not relevant to the question in front of the committee. Also, to the best
of my knowledge, this sentence was not discussed during the AC call - I'd have raised
my objection back then. Also, on its substance, we do not have any research or
other information available to us that would support a statement about frequent
rollovers.  Finally, it is unclear that 'static configurations' are at the core of the
operational issue or the 8145 observations, respectively.

RZERC might want to engage in discussing a shift to frequent rollovers (and now that the
Board has asked RZERC explicitly about KSK rollover, the fact that the rollover was
started before RZERC came into existent, seems no longer valid.  If the committee
members agree that the issue of frequent rollover is important, we should address the
issue in a proper advice, not en passant to the Board response.  Any immediate
remark would preempt a future, more elaborate response.

So, I consent to the text circulated on 31 July, provided the final sentence is removed.

Best regards,
    Peter
