Backporting openvpn from Noble to Jammy

[Jorge Merlino]

Hi folks,

I'm considering creating a backport of openvpn 2.6 from Noble to Jammy. 
This is because openvpn 2.5 does not work with openssl 3 in Jammy when 
FIPS is enabled. I managed to patch openvpn 2.5 to make this work but 
there are several patches to apply so this can be a hard sell for a SRU.

I have created the backported package and all works fine. My problem 
lies with the reverse dependencies of openvpn and how to ensure that 
they continue to work with the backported package installed. These are 
the dependent packages:

   eurephia
   collectd-core
   openvpn-systemd-resolved
   openvpn-auth-radius
   openvpn-auth-ldap
   fbx-all
   network-manager-openvpn

and all install cleanly with the new version. Can you give any advice on 
how to verify that they will work?

Thanks
	Jorge
