Preface
|
||||
=======
|
||||
I (Brent Saner) 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,” footnote:[See http://catb.org/jargon/html/Y/yak-shaving.html] indeed.
|
||||
|
||||
A lot of research went into how low-level boot operations take place when writing BDisk, both in BIOS and UEFI footnote:[*Unified Extensible Firmware Interface.* UEFI is not BIOS, and BIOS is not UEFI.] (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. The latter is what this project and documentation refer to when the word “BDisk” is used.
|
||||
|
||||
When I rewrote BDisk in Python 3.x (I should take the time to note that I am still quite new to Python so expect there to be plenty of optimizations to be made and general WTF-ery from seasoned Python developers), one of my main goals was to make it 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!).
