Suricata

I'm not convinced this is worth the effort. Other Debian based distro's may have different package naming/versioning. The blacklisting can already be disabled by specifying --with-libpcre-includes/libraries on the configure line.

So we're keeping it as it is?

There is a workaround for sure.
Not sure of the effort needed - Jessie would not change the naming most likely but other versions might indeed which can result in bigger (per version) support effort. So if it is going to become one of those (and looking into variations of minor versions of the pkg) - I would rather not chase it further.

On the other hand Jessie is going to be stable for a while I suspect so wondering if there is a an "easy" way out?

I guess we should leave it as it is, the workaround is fine and could be applied by the suricata package maintainer as well.
And no one complained yet :)

It would mess up the config a bit and thus I would keep it the way it is for now.
