It operates the mozilla-rootcerts installer script in order to allow
managing the resulting output openssl certs with the package tools.
Since openssl does not support more than one directory of certificates
(sheesh) this is an abusive package - it installs directly into the
openssl certs directory even though this is a sysconfig directory that
should normally only be touched using the config files infrastructure.
And, for native openssl, it's in the root /etc outside of $PREFIX.
Nonetheless, having this package is better than not having it.
Probably at some point this and the mozilla-rootcerts package should
be folded together in some fashion; but I didn't want to do that up
front, and in particular I didn't want to muck with the installer
script in mozilla-rootcerts any more than necessary to make this
package possible. This in particular prevented e.g. installing the
certs in share/ and symlinking them into the certs directory.
As things are, if you already have the certs installed manually you
can install this package over them cleanly, and thenceforth not have
to update them by hand.
