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.

What file systems are you using on your devices and why? (en.wikipedia.org)

I want to learn more about file systems from the practical point of view so I know what to expect, how to approach them and what experience positive or negative you had / have.

I found this wikipedia's comparison but I want your hands-on views.

For now my mental list is

NTFS - for some reason TVs on USB love these and also Windows + Linux can read and write this
Ext4 - solid fs with journaling but Linux specific
Btrfs - some modern fs with snapshot capability, Linux specific
xfs - servers really like these as they are performant, Linux specific
FAT32 - limited but recognizable everywhere
exFAT - like FAT32 but less recognizable and less limited

I use Btrfs for my root partition to be able to rollback if something goes wrong after update. XFS: in all other cases, since I hate the lost+found directory on ext4. Although I don't think there's any significant difference between ext4 and xfs in performance and reliability.

I'm curious now about BTRFS.

How do you roll back in case of problems?

[–] [email protected] 1 points 4 months ago

Take snapshot. If problem occurs, manually change boot label to use snapshot label.

Basically, I just followed this tutorial for my EndeavourOS installations. It's as easy as choosing an older entry in GRUB. Fedora offers something similar by default, and I think Tumbleweed does too.

Moreover I'm now playing with Arkane Linux (https://arkanelinux.org/), immutable flavour of Arch, it features another magic with btrfs and rollbacks without snapshots and GRUB

Oh ok cool! I'm going to check it out.

I'm taking a lot of notes for my next install. Trying to build something solid with Kubuntu.

Bookmarking Arkane. I'm a huge fan of Fedora Atomic but miss AUR.
