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

I've never had a problem with ext4 after power failure.

Zram is not a substitute for swap. Your system is less optimal by not having at least a small swap.

Firewalls should never default to on. It's an advanced tool and it should be left to advanced users.

Not to mention how much grief it would cause distro maintainers. If they don't auto configure the firewall they get blasted by people who don't know why their stuff isn't working. If they auto configure they get blasted by people upset that the auto configurator dared change their precious firewall rules. You just can't win.

I have a question about swap.

My current rig has 64 gb, and I opted to not create a swap partition. My logic being I have more than enough.

The question is does swap ever get used for non-overflow reasons? I would have expected 64 GB to be more than enough to keep most applications in memory. (including whatever the kernel wants to cache)

I believe so, though I went without swap for a while myself and never noticed any issues. When in doubt a 1gb swap partition can't hurt.

Start with a small swap file (100 MB) and see how much gets used, no need to waste 1 GB.
