Preface
About the Author
I am a GNU/Linux Systems/Network Administrator/Engineer- I wear a lot of hats. I have a lot of side projects to keep me busy when I’m not working at ${dayjob}, mostly to assist in other side projects and become more efficient and proficient at those tasks. “Shaving the yak,” [1] indeed.
A lot of research went into how low-level boot operations take place when writing BDisk, both in BIOS and UEFI [2] (and corresponding concepts such as Secureboot, etc.) which is no easy task to understand and very commonly misunderstood. (For instance, a common misconception is that UEFI necessarily implies Secureboot. This is quite far from the truth and UEFI by itself is quite a useful replacement for BIOS). I invite you to do research into the specifications yourself; it’s rather fascinating.
What is BDisk?
BDisk refers to both a live distribution I use in my own uses (for rescue situations, recovery, etc.) but foremost and most importantly, it also refers to the tool I use for building that distribution. In other words, it’s both a complete GNU/Linux distribution you can run entirely from USB/CD/DVD/etc. (without needing to install it to your hard drive)… and also the name of a tool to create a custom GNU/Linux install. The latter is what this project and documentation refer to when the word “BDisk” is used.
This documentation was started when I rewrote BDisk in Python 3.x; versions 0.x-2.x of BDisk were written in Bash, and horribly inelegant and rigid. [3] One of my main goals was to make BDisk as easy to use as possible. This is surprisingly hard to do- it’s quite challenging to try to approach software you’ve written with the mindset of someone other than you.
It’s my hope that by releasing this utility (and documenting it), you can use it and save some time for yourself as well (and hopefully get the chance to learn a bit more in the process!).
