RFC: Proposal: Install a /etc/ssl/cert.pem by default?

Hi,

Currently, FreeBSD does not install a default /etc/ssl/cert.pem
because we do not maintain one ourselves.  We do, however, provide a
port, security/ca_root_nss, which have an option to install a symbolic
link as /etc/ssl/cert.pem -> /usr/local/share/certs/ca-root-nss.crt,
which is not the default option.

This become a problem when applications, e.g. fetch(8), have grown the
support of doing certificate validation.  I think now it makes sense
to have a default cert.pem installed with the base system.

So my proposal would be:

1. Import a set of trusted root certificates, and install if
MK_OPENSSL is yes, to /usr/share/misc/ca-root-freebsd.pem;

2. In src/etc/Makefile, automatically create a symbolic link if it's
not already present in ${DESTDIR}/etc/ssl;

3. Teach mergemaster(8) and other similar applications to create the
symbolic link on demand;

4. Change the install/deinstall behavior of security/ca_root_nss:
   ETCSYMLINK checked: If /etc/ssl/cert.pem exists, back it up on
install then overwrite with new symlink, and restore on deinstall.
   ETCSYMLINK unchecked: If /etc/ssl/cert.pem do not pre-exist,
install new a symlink; on deinstall, if
/usr/share/misc/ca-root-freebsd.pem exists, replace the symlink with a
symlink to there, or remove if the file does not exist.

Comments/objections?

Cheers,
