This is HPR Episode 1888 entitled Linux from Crash.
|
||||
It is hosted by first-time ghost Brian in Ohio and in about 7 minutes long.
|
||||
The summary is my experience of installing Linux from source.

Hello HackerPuppetGradio, Brian in Ohio here, long time HPR listener, first-time host.
|
||||
At that time I talked to you about my experience of building a GNU Linux system from source
|
||||
using the Linux from scratch distro.
|
||||
My first attempt at building a Linux system from source was PocketLinux.
|
||||
PocketLinux is a guide found at the Linux documentation project.
|
||||
It walks you through the process of building a Linux system from source onto three and
|
||||
a half inch floppy's, hence the name.
|
||||
The guide is still available and can be found at TLDP.org, a link is in the show notes.
|
||||
PocketLinux is a fun project.
|
||||
There's nothing like hearing linus say linux on a system you've built from source.
|
||||
In the end, PocketLinux is very limited.
|
||||
It's limited in its size and it's limited what one can do.
|
||||
It's not able to replicate itself.
|
||||
That's where a Linux from scratch comes in.
|
||||
If PocketLinux is fun, Linux from scratch is serious.
|
||||
A number of years passed after PocketLinux in which I moved from being a Ubuntu user
|
||||
to being a dedicated Slackware user.
|
||||
I love Slackware and I can't see any reason to move away from it as my daily drive.
|
||||
Slackware lets you install compact Linux systems.
|
||||
It gives you good control over what programs are installed on your system.
|
||||
But a full Slackware install does add many programs that you may never use or understand
|
||||
or want.
|
||||
This led me to thinking about doing Linux from scratch.
|
||||
Building from source guarantees that only what you want is on your computer.
|
||||
The Linux from scratch distros a book that can be found at linuxfromscratch.org.
|
||||
The latest stable release can be found there and will guide you through the process of
|
||||
putting your system together.
|
||||
I won't bore you with the details.
|
||||
I'll just give you my overall impression and things I learned along the way.
|
||||
And if you're looking for an install ISO, you need not apply.
|
||||
If you decide to tackle Linux from scratch, you'll need a few things to get the job done.
|
||||
You have to have a functioning computer with a Linux system installed.
|
||||
I'm biased and think Slackware is the best place to start.
|
||||
If you can install a Slackware system, you have got most of the skills needed to build
|
||||
Linux from scratch.
|
||||
If using F-DIS or seeing N-Cursor screens makes it queasy, you might want to hold off
|
||||
on Linux from scratch.
|
||||
As far as the computer goes, it doesn't have to be the newest and shinest.
|
||||
But if you have a Linux running on it, it is a candidate for rebirth.
|
||||
In my case, I used an IBM T30 laptop.
|
||||
It's solid hardware with a few interesting features like sliding carts for CD-ROMs and
|
||||
floppy drives.
|
||||
It has a legacy parallel port and a legacy serial port as well as USB.
|
||||
And most importantly, it was cheap.
|
||||
Well, now that you've gathered the tools, you might ask, what skills do I need to build
|
||||
LFS?
|
||||
Do I need to be some kind of command line guru?
|
||||
Here's what I think.
|
||||
First and foremost, you need to be able to read and follow directions.
|
||||
The LFS book is well written, and I think anyone can get through the process.
|
||||
But you do need to read and follow directions.
|
||||
Take your time.
|
||||
Read and read, read the steps at the beginning of each section.
|
||||
Getting those foundational steps done right will save you heartbreak later.
|
||||
I can attest.
|
||||
After re-entering the cheat route environment in the middle of the build incorrectly, I was
|
||||
left with a subtly broken system that wasn't discovered until deep into the build process.
|
||||
This led to a trail of tears.
|
||||
As far as the actual command line goes, if you can move around the Linux file system,
|
||||
make files and folders, understand things like permissions, create users, you're well on
|
||||
the way to being able to build Linux from scratch.
|
||||
If confronted with a problem, your first answer is SUDU app get install.
|
||||
You might need to brush up something.
|
||||
Luckily, Hacker Public Radio has many episodes on using the command line.
|
||||
One utility and skill that I found essential to building Linux from scratch is the general
|
||||
purpose mouse.
|
||||
The first time I ever encountered this utility was installing Slackware.
|
||||
Near the end of a Slackware install, you're confronted with a question that says something
|
||||
like, do you want console mouse support on boot up?
|
||||
I really didn't know what it meant.
|
||||
And it wasn't until I built an LFS system that I really began to appreciate the power
|
||||
of cut and paste in the console.
|
||||
The first time I tried building LFS ended in a complete failure.
|
||||
Trying to type in a long picket fence SUD command ended in frustration and brought the
|
||||
whole project to an end.
|
||||
Cutting and pasting between consoles made Linux from scratch possible for me.
|
||||
It's not hard to use the console mouse, but it's different than a GUI mouse, and it takes
|
||||
a little practice to get used to it, and I think it's essential to an LFS build.
|
||||
So in the end, after you take your time, read, and not consume too many adult beverages
|
||||
while you're building from source, you too can build a Linux system from scratch.
|
||||
Ours of dot slash config, make test, and make install will get you there.
|
||||
And as an added bonus, watching GCC output beats anything on TV these days.
|
||||
So what are you left with on your first boot up?
|
||||
You're left with a very minimal system.
|
||||
Even the maintainers admit that.
|
||||
Beyond Linux from scratch, also at linuxfromscratch.org, we'll take you to the next level.
|
||||
BLFS guided me into adding enough programs to be able to record and upload this podcast.
|
||||
My system is growing, but at a measured rate.
|
||||
When every program takes time to build, it makes you think more about what to add and why.
|
||||
And I think it's a good mindset.
|
||||
It's so easy to get into the install the newest app, use it a couple of times, and forget
|
||||
about it, way of doing things.
|
||||
Linux from scratch will cleanse you of this habit.
|
||||
LFS also helps you to appreciate when the virtues of open source software, the source
|
||||
code.
|
||||
I'll admit, the first time through LFS, you're not looking at source code.
|
||||
You have one and only one thing on your mind, getting or done.
|
||||
But now, as I've expanded my system, I do take the time to read the readmes and the
|
||||
install notes of these programs we hold so dear.
|
||||
So what's in the feature for my LFS system?
|
||||
I'd like to learn more about package management, and I'd like to try to learn about automating
|
||||
the build process.
|
||||
I think it'd be really cool to start a script and come back a couple of days later to a
|
||||
shiny new command prompt.
|
||||
In conclusion, I know LFS isn't for everyone, but the book is worth reading no matter what.
|
||||
It gives details to how Linux space systems work and are held together that any Linux
|
||||
user can benefit from.
|
||||
Thanks for listening, and I know the lady in the outro will say, email me if you have
|
||||
a comment, but I say, record a podcast.
|
||||
It's fun.
