LFS 4.0 Released

Tekmage writes "For those of you who have never had the pleasure of rolling your own Linux install from scratch, take a moment to check out Version 4.0 of Linux From Scratch. Definitely for the techies amonst us, there is (IMHO) truly no better way out there to get down and dirty with the inner workings of our favorite OS." LFS organizes its documentation into "books"; 4.0's book is dated yesterday.

educational value

[mrm677]

LFS is a great way to learn Linux. It truly helped take me to the next level of my personal understanding of how things work.

However I would never recommend it for a production system. Even using it for a personal workstation takes loads of time to manage. One doesn't appreciate package management until they have installed a LFS system!!! Of course one could always use RPM/APT/DEB after doing a LFS installation...

Ditto on the educational value. I'd been using Linux in various forms since '93, but it wasn't until I started exploring LFS that I really began to understand and appreciate what went on behind the curtain.

I'd argue the "never in a production system" point though. For an average end-user, sure. But if you have a particular end use(r) in mind (robot control, wearable computer, multimedia entertainment, home automation, etc) then it may be easier to enhance an LFS recipe than prune back a generic distro.

I beg to differ. I'm running LFS (a CVS version from early August) on a small-time production web/email server. It was much simpler to set up than RedHat because I knew exactly what was being installed where, and I had configured everything myself. It took the better part of the day to compile LFS and the other packages necessary to set up the server, but it was ready to go the minute I was done compiling.

It's been up and serving for 38 days straight. It was up for a month straight before that, but I had to bring it down to add memory and remove the cdrom drive.

I'm also running LFS on a desktop machine. It's not as pleasant to use as the server (KDE took 8 hours to compile), but it was definitely worth the effort it took to set up in terms of learning, stability, and configuration flexibility.

I appreciated package management a LOT more before I started using LFS. I got into LFS originally because I got sick of Mandrake installing hundreds of packages I didn't recognize or need. I want to know exactly what's on my system and why. And I hate when a package refuses to compile or install due to dependencies which shouldn't be failing. I've never had that happen in LFS.

LFS definitely has a steeper learning curve than pre-built distros. But what it loses in initial ease-of-use, it more than gains in long-term stability and simplicity. I wouldn't recommend that someone do their first (or second or third or fourth) LFS build on a production server, but after experimenting with it and really learning how it works, I can't go back.

YMMV, obviously. Not everyone is paranoid and anal like I am.

What do you want them to start from? Flip 0's and 1's on a front panel?

In order to build ANYTHING you need an existing tool chain. Here that means gcc, bash, ld, etc... LFS starts with creating a bootstrap system using your existing distribution: this existing distribution might just be a bootable ISO cd. LFS DOES go through everything: the kernel, gcc, glibc, ... everything.

LFS will show you how to build your own Linux, step by step. It will tell you everything you need to know to understand the bootup process.

If you want to run LFS on a 486 though, you'd probably be a lot better off getting it going from your main system, and then copying over. glibc alone can take HOUR(S) to compile on a modern system.
