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?

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
Bookmarking Arkane. I'm a huge fan of Fedora Atomic but miss AUR.
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.
Take snapshot. If problem occurs, manually change boot label to use snapshot label.
