Subject: [PATCH] Subpackage minimal set of daemons into -minimal

For the users directly interacting with pluto through whack, such as
Submariner, pulling in the entire systemd dependencies upon installing
libreswan occupies unnecessary amount of disk space. This splits the
minimal portion of the package without systemd into a -minimal
subpackage.

Resolves: RHEL-5299

+%description minimal
+Libreswan is a free implementation of IPsec & IKE for Linux.  IPsec is
+the Internet Protocol Security and uses strong cryptography to provide
+both authentication and encryption services.  These services allow you
+to build secure tunnels through untrusted networks.  Everything passing
+through the untrusted net is encrypted by the ipsec gateway machine and
+decrypted by the gateway at the other end of the tunnel.  The resulting
+tunnel is a virtual private network or VPN.
+
+This package contains the minimal set of daemons and userland tools
+for setting up Libreswan.
