Hi, i am thinking of switching to gentoo, and wanted to ask if its a good idea. Anything i should look out for?
Btw im coming Form arch
Thx :3
@Twakyr I’ve been a hardcore gentoo user/fan for 20+ years, I thought I’d never be able to use anything else till I started playing with Nix this year. The granular configurability of each individual package has yet been unmatched for me in any other distro till Nix. For #gentoo though, I’d highly recommend taking great care in tailoring your
/etc/portage/make.conf, setup/etc/portage/repos.conf/gentoo.confwithsync-type = git, and use/etc/portage/package.{use,mask,unmask,accept_keywords}as directories for individual packages. I tend to keep a/etc/portage/package.mask/failedfile for upgrade blockages fer me to unfuck after aemerge -avuDUN @worldsucceeds.As a noob to Linux, reading Gentoo Handbook & Arch Wiki has made me not only understand a PC better in terms of software management of hardware but understand Linux. I am nowhere near being able to actually use Gentoo. I installed Arch once, that been far enough for me with Linux. I know the people that wrote those guides need to be funny for Presidency because this is how we need to run the world. LOL
Does seem like being funny helps with running for president these days
Not bad actually, but enable binary packages to speed up compilation.
If I could give only one reason to use Gentoo, it would be the community.
Anyway, if you choose this route, read the handbook through like a book first. Get an idea what you want your endpoint to be, then start.
I used Gentoo for a few years. I don’t recommend it at all!
first off, there are no tangible advantages. it’s not faster. it is more customizable (by use flags), but the only tangible advantage of those is bragging rights saying you kept a certain library off your system and saved 100kb. just enabling all features is more practical.
there are tangible disadvantages. a big system upgrade can take days. and often fails. and, the manual time you spend merging config files with dispatch-config is large.
I switched from Gentoo to debian after 3y of using Gentoo. i switched from debian to arch after about 10y later. been on arch for about 6y now. would not recommend Gentoo
Those things you listed are part of the fact, not all. Like saving 100kB. It does not matter in your 1TB hard drive, but it’s night and day in embedded systems. No benefit for you isn’t the same to no benefit.
the 100kb u save from the right use flags is nullified by the hundreds of mb needed to have the entire build tool chain on your system. there are dedicated distros for embedded systems that are much better suited. like alpine Linux. or LFS. (IIRC with LFS u can get the entire system installed 2 or 3 MB)
I mean, you can cross-compile to generate a Gentoo rootfs for the embedded system.
I worked on embedded systems for audio devices. I of course endorsed Alpine as well, but with musl as the C library I got weird bugs of stuttering audio output.
With Gentoo I get the option to build my entire system with musl as well, but I would rather have that bug not in my system. That’s what Gentoo offers: options.
By “LFS”, I think you mean Buildroot, practically. Buildroot is also highly customisable, but Buildroot isn’t a distro. Like LFS, there is no way yo update a system, only rebuilding with latest packages. It also does not have flags for the whole system, so you’re on your own if you want to disable, say IPv6, in the whole system.
Gentoo is very much like an manual transmission. If you ask anybody that drives manual they will say 1 of 2 things “i like it because it gives me control” or “i use manual because i always have”
I love gentoo as playing around and trying stuff out. My personal recommendation is use ZFS or btrfs for a file system and have subvolumes. So if you get so lost in the rabbit hole you can climb back up.
If your philosophy is" stable and mine!" Gentoo is for you. You can build a distro, with all the packages you want and once your done if you decide to update every month and dont care a whole lot about bleeding edge. It will work really well, it you want bleeding edge, you can have portage use ustable packages with a stable system. But you really must know what your doing or you WILL BREAK STUFF.
I ran gentoo for 6 months then went to debian, its a great learning tool for understanding how linux works under the hood. I would also recommended systemd over openrc. Its not that openrc is bad, its just alot of extra work for simple things to work.
Gentoo to me is more a messing around on a spare computer distro, than a production computer. Not that it cant be production, but im personally very lazy when i just want to use my personal pc.

Take your time with the install process. It’s possible that you may breeze through it. It’s also possible that you may discover that, say, there’s something wrong with the EFI implementation of the system you’re installing to that you need to do some research to resolve. I’ve had both experiences.
Once installed, Gentoo is pretty much rock-solid, and almost any issue you have can be fixed if you’re willing to put the effort in. Portage is a remarkably capable piece of software and it’s worth learning about its more esoteric abilities, like automatic user patch application.
Do take the time to set up a binary package host. This will allow you to install precompiled versions of packages where you’ve kept the default USE flags. Do everything you possibly can to avoid changing the flags on webkit-gtk, because it is quite possibly the worst monster compile in the tree at the moment and will take hours even on a capable eight-core processor. (Seriously, it takes an order of magnitude more time than compiling the kernel does.)
Install the gentoolkit package—equery is a very useful command. If you find config file management with etc-update difficult to deal with, install and configure cfg-update—it’s more friendly.
If you’re not gung-ho about Free Software, setting
ACCEPT_LICENSE="* -@EULA"(which used to be the default up until a few years ago) in make.conf may make your life easier. Currently, the default is to accept only explicitly certified Free Software licenses (@FREE); the version I’ve given accepts everything except corporate EULAs. It’s really a matter of taste and convenience.Lastly, it’s often worthwhile to run major system upgrades overnight (make sure you
--pretendfirst to sort out any potential issues). If you do want to run updates while you’re at the computer, reduce the value of-jand other relevant compiler and linker options to leave a core free—it’ll slow down the compile a bit, but it’ll also vastly improve your experience in using the computer.(I’ve been a happy Gentoo user for ~20 years.)
It’s thanks to Gentoo that I’ve been a Linux sysadmin for over 20 years. That being said, I’ve since moved to Arch and then Debian.
Some points: On modern systems you won’t really notice any speed improvements from custom compiling the packages. Apart from maybe some numbers in articial benchmarks. On old systems with very limited resources, you can eke out a bit of more performance. Back when I was still using Gentoo, my proudest moment was getting a Pentium 1 with 96MB Ram (Yes, MB!), which was a gift of a colleague to his broke brother, into quite a useable little machine. Browsing, listening to MP3s, email, some simple games.
I also noticed a noticable improvment in performance in a 400mhz Athlon I had setup for my mom.
That being said, I was only able to do this, because I was using distCC to distribute compiling across several machines to keep compile times to a somewhat sane level. Also, I was doing a unpaid internship at the time, so I basically had all the time in the world, so compile times didn’t really bother me.
I had tried to use linux before. After Windows XP crashed one too many times. I decided to see how things work on Linux. I initially chose a “easy to use” desktop distro. (Mandrake Linux). Got everything setup. Even 3D Accelaration worked. Everything was really nice and fun. Then I tried to tinker under the hood and I broke something that I couldn’t figure out how to fix. So I thought, maybe I need to find something even easier, so I chose Suse Linux. Same story. Set everything up. Desktop working, 3D working, etc… start to tinker, break something, back to square zero.
Then I decided to change my approach and choose the hardest distro. The choice was between Linux from Scratch and Gentoo. Linux from Scratch sounded waay to painful, so I chose Gentoo.
It took me 3 days until I had a somewhat working system without a desktop. Then another 3 days until I had a desktop running Fluxbox.
But the learning experience was invaluable. Being forced to use the CLI and not only that, but more or less configure everything by hand. It takes aways the fear of the CLI and you get a feel for where everything is located in the filesystem, which config files do what, etc… It demystifies the whole thing substantially.
You suddenly realize that nothing is hidden from you. You are not prevented from accessing anything or tinkering with it.
The downside is that Gentoo takes a lot of time and effort to maintain. But the learning potential is invaluable. Especially if you use it to also start doing little projects in linux. e.g. File server, router, firewall, etc…
Me knowing Gentoo, got my first real job as Linux Sysadmin and before long I was training rookie Admins. And the first thing I always did with them was to run them through the Gentoo bootcamp.
Once they go to grips with that, everything else wasn’t that difficult.
No advantage over Arch IMO.
If you want to play with it, setup a VM.
Happy with gentoo moved back after 14 years away, (ran 2003->2009, 2023->now) I like it because I can easily and sustainably make anything a package and build it as minimal as I like, along with easily modify packages (ebuilds) and flags as needed.
Gentoo user since forever.
The most consistent and long time solid distro, IMHO.
I use it everywhere I can, from servers to laptops. It’s so flexible and predictable that I simply love it.
Nowadays emerging stuff is so fast that I wonder why bother with binary packages at all. Once, when compiling Firefox took DAYS well… But in today’s hardware, meh.
;)
Are you looking to learn linux more or have a easy living experience, or what is the goal? If you want to get to know linux, learn how to compile a kernel, make your own initramfs and such, then: absolutely! If you want a stable easily maintainable system, then… maybe not. Like it is possible, and Gentoo is very stable, but if you are just starting, then you may make choices that do break when you upgrade. With some experience, this will go away, but expect some downtime in the beginning.
I want a learning experience and a challenge. And customise EVERYTHING!
Then go for it! Gentoo is a wonderful option for that goal.
I’d probably recommend LFS over Gentoo for that—you do more “yourself” and I found the LFS instructions easier to follow than the Gentoo install guide. And I’d say I learned more about Linux from LFS than from installing Gentoo. But LFS was done over about a month or so for me (not nonstop ofc, just in my free time) whereas Gentoo was 1 or 2 days.
It’s a great distro. You don’t have to compile; lots of packages are available as binaries, but having the option to compile the latest version of things is cool. Definitely worth a try, especially if you were using arch before.
I would definitely conpile everything from source
Comments complaining how everything takes time to compile in Gentoo are kind of funny, do you really need everything to be installed asap?
That being said, Gentoo indeed is not for everyone. I’ve been using it for +15 years and am really happy with it - almost zero maintenance and it’s super stable. The crux is the time it takes to be installed and people hold a weird grudge against it just for that.
But at the same time there are more distros oferring pretty much the same, i.e. your own arch.
