From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Your chosen desktop Linux defaults? (lemmy.zip)

What are your 'defaults' for your desktop Linux installations, especially when they deviate from your distros defaults? What are your reasons for this deviations?

To give you an example what I am asking for, here is my list with reasons (funnily enough, using these settings on Debian, which are AFAIK the defaults for Fedora):

  • Btrfs: I use Btrfs for transparent compression which is a game changer for my use cases and using it w/o Raid I had never trouble with corrupt data on power failures, compared to ext4.

  • ZRAM: I wrote about it somewhere else, but ZRAM transformed even my totally under-powered HP Stream 11" with 4GB Ram into a usable machine. Nowadays I don't have swap partitions anymore and use ZRAM everywhere and it just works (TM).

  • ufw: I cannot fathom why firewalls with all ports but ssh closed by default are not the default. Especially on Debian, where unconfigured services are started by default after installation, it does not make sense to me.

My next project is to slim down my Gnome desktop installation, but I guess this is quite common in the Debian community.

Before you ask: Why not Fedora? - I love Fedora, but I need something stable for work, and Fedoras recent kernels brake virtual machines for me.

Edit: Forgot to mention ufw

Swap holds memory pages which are not currently used. Putting them out of the way will optimize the main RAM for normal operations.

It's not a huge difference on a modern fast system with lots of actual RAM but it can be felt on older systems and/or less RAM.

So it's not not having swap that makes the system "less optimal" but not having enough RAM if I understand correctly?

They go hand in hand. Given enough RAM you can keep the swap in RAM rather than on disk to make it faster, but you still need swap.

I'm confused, so if there's no swap, what is the system doing given enough RAM? What's the impact?
