Installing Ubuntu 16.04 with btrfs using debootstrap

Partition layout

First, create a GPT partition table.

1. boot partition, label: EFI, flags: boot + ESP; size: 1GB, format to FAT32;
2. root partition (label: root), must same size on all devices!
3. swap partition.

Update

The talk never happened, but I wrote an article on this topic: http://amitsaha.github.io/site/notes/articles/python_linux/article.html

Introduction

Most of the information that a power user or a sysadmin may need to know about a running Linux system is available in the form of plain text files. Utilities such as 'cat',' head', 'less' and 'grep' are sufficient to mine information that one may need from these files. Things however can get unwieldy when the task at hand demands writing shell scripts to couple these utilities. As much as power Linux users (including yours truly) would absolutely love to master shell scripting, the learning curve is quite steep and can be cryptic. This is certainly an opportunity to explore other ubiquitous alternatives for stitching together utility scripts. Bring in Python.
