Hi,

Looking at this "blanket" change I'm not sure this is a good way to bring in without discussion
and especially without a revision change:

https://cgit.freebsd.org/ports/commit/security/ca_root_nss?id=574c939eccd322

The relevant bug was reported here:

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=262755

And I'd suggest rolling back that recent change or making a better effort at explaining the
problem it solves.


Cheers,
Franco
