Gentoo Linux

Hello :)

I just finished my first arch install I wanted to set my sights on something more challenging. So, I booted a live image with QEMU Virtmanager to try out gentoo, and after reading the wiki I thought to myself “man i should have started with gentoo”

The arch wiki is good in its own right, but as a beginner i felt really confused and overwhelmed. I felt like I had to google terms just to catch up. The gentoo wiki, however, is really good at explaining concepts and the overview of the technology. When the Arch wiki just says “use mkfs.ext4 /dev/sda2” or something the gentoo wiki actually explains what sda, sdb, etc and ext4 means. I sort of learned it the hard way with arch, but i learn and understand lot more from the gentoo wiki. I love that it explains partition tables, filesystems, heck it even explains what is an IP in the networking section. Making a gentoo system and reading the wiki is basically an interactive computer science course lmao

So, thank you gentoo wiki :)

--autounmask tells emerge to show you what you should add to your package.accept_keywords in order to unmask masked packages.

--autounmask-write tells emerge to automatically modify package.accept_keywords and package.use. You still need to apply the changes using dispatch-conf, since Portage's config files are protected by CONFIG_PROTECT.

{,-write} tells bash to duplicate the argument, adding to the first argument and -write to the second.

What causes the tremendous amount of rebuilds when a new version of ICU is released?

It always seems to be a problem and takes weeks before it seemingly disappears on its own...

I ask Google Bard "What's the difference between Funtoo and Gentoo?"

Bard replies: Both Funtoo and Gentoo are Arch Linux-based distributions known for their source-based installation and high degree of customization. While they share a lot of similarities, there are some key differences to consider:

I checked, and both Gentoo and Arch initially released in March 2002, although Arch is older by 20 days.

I've been interested in switching away from $PROPRIETARY_VENDOR's HPC node / cluster management offering for a while, and the opportunity has finally arisen - $VENDOR has decided to massively hike up their prices, so it's time to look at alternatives.

The top option on my list is Warewulf. Warewulf is a stateless node management tool, where stateless means "we boot any image you want into memory" (compared with competing implementations which do 'magic' to image a node's disk every boot). There are advantages and disadvantages to each approach.

The thing that attracts me most to Warewulf is that they've come to the conclusion that most HPC "disk images" are basically container images. Rather than using a chroot directory as an image (as do so many competing implementations) Warewulf have leaned wholeheartedly into the concept, and have adopted the OCI image tooling to define HPC images!

This offers an astounding amount of flexibility that the current $VENDOR solution does not - the ability to define, build, and run any (reasonable) flavour of Linux as an image for HPC nodes; images need only the kernel, networking, systemd, and (optionally) a nfs client (this is for convenience, it's not required for node functionality).

Based on that I've taken it upon myself to have some fun and investigate the current state of Warewulf as a node management tool - the first step, of course, was creating a Gentoo ebuild for Warewulf that compiles and installs. I'm happy to say that, after fixing some bugs in the offline build process, I have a working ebuild.

If you're a Gentooer with an interest in Node Management or HPC, please give my Warewulf ebuild a try; it compiles and installs but I haven't yet had a chance to do any real cluster management and I'm interested in hearing about any bugs you encounter!

Next Week(-ish): Gentoo HPC Base Images - I'm going to have to dig into Gentoo Networking to update the wwinit image.

Hey everyone, I've been using an Arch system for the past 2 months and I've had an absolute ball learning more granular details about my hardware. Never in my life did I think I'd be looking at kernel modules and contemplating swapping out init systems and trying different kernels.

I write this post somewhat open-endesd because I'm clueless as to where Gentoo can take me in terms of hardware acceleration and help me learn development of software/firmware deeper. To my understanding, everything must be compiled from source code, which I'd like to learn more about as well. Ive dipped my toe in a myriad of programming languages too and found a more terminals focused work flow was ideal.

My major use cases for my computer are to benchmark hardware and pick more features in software that I'd have to compile from source anyways. I do work in molecular dynamics from time to time and have used software distributions like GROMACS and LAMMPS. Any advice that could be wouldbbe greatly appreciated. The thoroughness in the Gentoo Wiki's documentation is amazing, but its a overwhelming lol

My foundation is a little like swiss cheese though. Don't know what I don't know! Looking forward to becoming a part of the Gentoo community. I'd love to develop software like DWSIM someday.

Heya Gentoo Crew,

Looking for some moderators to help me out.

It's a pretty chill community, myself being one of the main posters. So should be easy.

Let me know in the comments if you want to help out.

Hi ! I'd like to have a Gentoo computer. But also in the future a Gentoo cell phone. Why not a Gentoo home console?

Is it possible to provide all this hardware with pre-compiled updates with a NAS that would do this automatically periodically?

I have the impression that with Gentoo, I'll be able to create tailor-made systems for my devices, and it gives me lots of ideas, but compiling on all these machines makes me feel a bit cold

Sorry if this is a silly question, I'm neither a developer nor an administrator, but I'd really like to learn how to tinker with my PC !

Recently got a laptop from a friend after mine got smashed to smithereens. I was going to do a fresh install of my favourite binary distro, Void Linux on it but I recently found out they dropped Monero (and Crypto programs) for ideological reasons.

I guess its time to come home!

Booted Laptop/PC to the LiveUSB, time to do my gruelling ZFS installs :)
