Are Minimal installs really better?

scottalanmiller

I prefer minimal in most cases. I'm tired of the bloat. Not because it takes up so much disk space, but that's where bad things happen. Tools having issues that I didn't need to have there at all.

Don’t you normally installed Fedora Server instead of minimal?

I dont know if that is true. If a tool lay dormant and/or a service isn't running what kind of affect will it have? I find myself needing additionally shit after a packer image has been created and all the supposedly needed stuff has already been added.

I think it's best to start with the smallest most basic thing and then add what you think you always need. That becomes your personal or company's minimal install and that might be larger or smaller than someone's else because we all need different things.

If we are talking Fedora Minimal Install then it's actually a pretty bloated affair compared to others like Debian for instance (only the base system, no extras). Even Fedora Custom Operating System option, which I assume is smaller than minimal, is bloated in comparison.

I have both installed on my test host in the latest versions and looking at dmesg Debian boots in 2.7 secs compared to Fedora's minimal/custom 9.7 secs. After boot Debian uses ~80MB RAM while Fedora uses ~240MB RAM. Fedora of course has more services running by default and pulls in more packages during install. Even Fedora Server's netinstall disk image is about twice the size.

I do on Fedora, but not on most things. I find that Fedora Server I use quite a lot of.

Minimal but not to the point of reaching alpine linux minimal. If you consider what is driving containers and everything it is about being very small and launch in seconds.. and they told me crazy when I spend hours making Windows xp and 7 as lite as possible 10 years ago and trimming the fat just to run single app like a game, i was such visionary.

Also even when you install something bigger, what you need isn't always there anyway.

I consider for instance screen to be a pretty basic tool. Not in Fedora Server.
nmap ? Not in Fedora Server.
tcpdump? Yes, it was there.
iperf ? No, not in Fedora Server.
smartctl ? Yes, it was there.

I think whatever you distro/installation options you pick, you are going to need to add stuff anyway. If that is part of the post-installation process then it's going to be there when you need it.

The problem is that when you have many different admins that use different tools. You might use Nmap while some people just want to use netcat. If netcat isn't installed, I probably wouldn't even think to use Nmap just because Nmap isn't standard. Nmap will also trigger the hell out IDS systems

Every admin is going to install their own shit and they will be configuration drift. If you had the full sever install there is arguably enough tools to do everything. Sure you are going to want to install a few packages, but not the amount you will add with minimal.

That's a company standard problem, not an OS problem.

If a couple of guys doing admin work on the same machines sit down and think through what they use, you could probably come up with a comprehensive list that makes everyone happy. Post-install those packages are added on every machine.

On a regular basis you review the package list and add stuff or remove stuff and that becomes the new standard. Then push it out to all servers with automation.

OK, I get it now.

Well, if you think Fedora Server is closer to what you want in a minimal install I don't see a problem using that instead. And then adding whatever is missing.

You get stuff like cockpit too but maybe that is something you always want.

I don't know if fedora has a list of packages that are added for each installation option.

It's not the whole truth though because some of these packages are installed in Minimal Install but they are listed as optional. I don't know when packages that are marked optional actually are installed or not. One example is the packages in the Standard group.

Ahh, good to know.

Anyway if one wanted something between minimal and fedora server but without cockpit, bluetooth and such, you could install minimal and then run dnf install @standard to get the packages from the standard group, which is most of the utilities.

BTW, it took less than 30 seconds to download and install the standard package on my test system. It's many packages total but they are small.

And also can do this during the software selection screen too.

Now there are some negative when installing standard groups. You end up having packages like these installed even though you are setting up a headless server.

Where was those? They were not in the standard group when I looked.
