+# The Debian ca-certificates package merely takes the CA database as it exists
+# in the nss package and repackages it for use by openssl.
+#
+# The issue with using the compiled debs directly is two fold:
+# - they do not update frequently enough for us to rely on them
+# - they pull the CA database from nss tip of tree rather than the release
+#
+# So we take the Debian source tools and combine them with the latest nss
+# release to produce (largely) the same end result. The difference is that
+# now we know our cert database is kept in sync with nss and, if need be,
+# can be sync with nss tip of tree more frequently to respond to bugs.
+
+# When triaging bugs from users, here's some handy tips:
+# - To see what cert is hitting errors, use openssl:
+# openssl s_client -port 443 -CApath /etc/ssl/certs/ -host $HOSTNAME
+# Focus on the errors written to stderr.
+#
+# - Look at the upstream log as to why certs were added/removed:
+# https://hg.mozilla.org/projects/nss/log/tip/lib/ckfw/builtins/certdata.txt
+#
+# - If people want to add/remove certs, tell them to file w/mozilla:
+# https://bugzilla.mozilla.org/enter_bug.cgi?product=NSS&component=CA%20Certificates&version=trunk
