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’m curious now about BTRFS.
How do you roll back in case of problems?
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.
