[Openswan Users] Backing up 2.2 before 2.3 upgrade

[tomk at runbox.com]

I've got 2.2 running just the way I like it on my laptop, with a NETKEY 2.6.9 kernel, but I'd like to give 2.3 a go for the klips support. I'd like to be able to fall back easily to my current 2.2 install, if things don't work out for some reason (i.e. I make a stupid mistake). So I'm planning to backup the following files/directories:

/etc/ipsec.conf
/etc/ipsec.secrets
/etc/ipsec.d/*
/etc/rc.d/ipsec
/usr/local/lib/ipsec/*
/usr/local/libexec/ipsec/*
/usr/local/sbin/ipsec
/usr/local/share/doc/openswan/*

Am I missing anything essential?

Thanks
Tom K
