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 started using it on my NAS and also on root. Then I switched my personal machine to ZFS on root. I manually created both setups (somehow). This is the worst part in my opinion. The best decision, though, was to ditch grub in favor of zfsbootmenu. Skips all the brittle steps with grub and its boot partition. Now I just have zfsbootmenu directly loaded by UEFI from the EFI partition. Everything important is directly on ZFS, including… well, everything. Can also use snapshots but I have not needed that yet.
