Not that I'm aware of.

I don't know if this is what Ian was referring to, but in theory we can leave the root certificate in NSS but set the "trust flags" off. This would result in rejecting any use of a certificate whose cert chain terminated in that root. Note that we've never actually done this for any root.

Oh right, I completly forgot about that. I think I was too concentrated about what the CA can do instead reading the question correctly...Ian indeed asked about NSS (he calls it root list :-) ).


Note also that (I think) in this case a user could manually set the flags back to allow the root to be used again.


Which isn't such a good idea. I think the only flag which should be allowed in such a case would be the email flag. But I remember from some bug that removal of the CA root nevertheless allows to read previously encrypted mail, provided the EE cert was marked accordingly.
