Overview

  • Introduction: Purpose and Terminology
  • Background: Quick Overview of uEFI and GPT
  • Enablement: Enabling uEFI and Creating GPT Disk Labels
  • Booting: Linux and Windows Tools and Solutions
  • Practices: Rod Smith's rEFI Boot Loader and Author's Eccentric Ways

The purpose of these materials is to focus on the following concepts, realities and practices.

Purpose

Adoption:
The [unified] Extensible Firmware Interface ([u]EFI) is here, and is virtually near 100% universal adoption. Knowing the firmware and booting realities are unavoidable, especially with an increasing number of uEFI-only systems lacking Compatibility Support Modules (CSM, legacy BIOS compatibility). The GUID Partition Table (GPT), whether used with uEFI or not (latter usually being non-bootable under CSM) offers many advantages too.

Familiarity:

Vector Graphics using Inkscape - 11 January 2014 NoVALug Meeting

On Saturday, 11 January 2014, the regular monthly meeting of NoVALug started, as usual, with an interactive monologue by Greg, bringing us up to speed on various current events topics. Most notable was the recent establishment of an association between Red Hat and CentOS. Greg filled us in on his take on the “What's in it for Red Hat?” side of the discussion, with input from Peter and others in the group. Then we got on to the main topic of the meeting – Inkscape.

NoVaLUG Site Survey

Over the next few months, we'll be upgrading the NoVaLUG website to Drupal 7.  As part of that update, we'll be looking at the everythign from the look and feel of the site to the features on the site to integration with other services.

As part of that update, we'd like some feedback from you, the NoVaLUG community, about what is good about the site and what is not so good, what you find useful, and what you find to be lacking.

This survey has five free response questions.  You may answer any or all of them.

What is your preferred desktop?

What is your preferred OS for a server?

Logo Design

We are looking for a logo. Please submit your ideas. If you aren't artistic, talk with a friend who is. We will use the logo on the website and make it available for purchase on items (at cost).

Temporarily stopping execution in scripts

One of our junior sys admins told me he was trying to figure out how to modify his monitoring script during maintenance windows (the monitoring script is called automatically by the monitoring agent on the box.) I told him to use a "stop file."

At or near the top of your script (a simple bash script,) put a block like this:

if test -f /tmp/do_not_run
then

echo "Ok"
exit 0

fi

Then, during maintenance windows, create the /tmp/do_not_run file and the script will simply exit without attempting to perform any actions against the system. When the maintenance window is over, remove the file and everything goes back to normal.
