The variables and functions belong to a block/file, this is their scope.
Both functions/variables you mention are actually unique within their
respective file scope. Also have a look at name mangling.

[CentOS] Eclipse (again)...
Hi Just thought I might ask my recent question about Eclipse again, only in a slightly different way: Is anyone here using the Eclipse version supplied with the CentOS 6 distro (as opposed to a build downloaded from www.eclipse.org)? Does it work for you? Are you able to install additional components via the built-in software setup mechanism?

Yes. I had things a bit wrong here.

I have a fair number of includes for named.conf; I have two views and other odds and ends. My thoughts are to make a directory; /etc/named.d to put all these includes into instead of 'dirtying' up /etc. This way the only files I replace/add to /etc are named.conf and rndc.key (I would like to work the latter around to also be in named.d, but this impacts rndc itself). >>> There is an /etc/named directory included in the bind package, I assume >>> that it is meant for this purpose... >> It is for your zone files, not necessarily for your named.conf >> includes.

I am reshaping my conf includes to go into /etc/named, rather than what I created /etc/name.d There is significant lack of consistancy as to where things are kept under /etc It seems there should be a better way so you don't have to change /etc/named.conf, but add files as needed to /etc/named but how is beyond me. This system is also my internal ntp server, and my notes from what I set up 3 years ago are too thin, plus now I have IPv6 to support. /etc/ntp.conf takes a lot of customization. This is definitely a week to pretend to be a wizard and stay up late. Or maybe that is my problem; staying up too late last week!
