Mark,
Yes, this is a good point. In a setup like this you are taking
responsibility for updates and patching yourself, just like you would for
any other set of libraries you use to develop an application. It becomes
local to your application and not something you can rely on the operating
system to provide, much like many java applications now come with a full
version of the JRE they need to work included.
This is the tradeoff you make, but it's not necessarily bad. You can use
the OS and patching infrastructure as the foundation for your app, then use
whatever you need to actually accomplish your business goal. If that one
part of the system needs to be customized, then so be it. After all,
that's the reason you're running the server in the first place.
