riak-debug - check /etc/default/riak (ulimit should be set there)

It is very common for Ubuntu users to forget to set ulimit -n 66xxx in /etc/default/riak

This adds an additional check for this file to riak-debug

@jpease does this sound like a good idea? Originated in ticket 9129 - wasted two CSE days.

No reason not to do this.
Because /etc/default/riak is an Ubuntu-specific thing, I'd say changing the second line to

[ `uname -a | grep -i "ubuntu" -c` -gt 0 ] && [ ! -f /etc/default/riak ] && dump etc_default_riak echo "error: /etc/default/riak missing"

Checking for distribution specific, undocumented strings is usually a bad idea. I'd just leave out the second line altogether. If the config file exists, collect it, otherwise not. Also, apart from Ubuntu, there are other distributions that make use of /etc/default, and the equivalent /etc/sysconfig exists on RedHat and SuSE.

I was under the impression that only Ubuntu or Ubuntu-based systems made use of /etc/default. As that seems to be an incorrect assumption, I agree that the second line should be left.
