# 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.

# Where possible, bump to stable/LTS releases of NSS for the last part
# of the version (when not using a pure Debian release).

# When triaging user reports, refer to our wiki for tips:
# https://wiki.gentoo.org/wiki/Certificates#Debugging_certificate_issues
