What file systems are you using on your devices and why?
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

ZFS all the things. On my workstations, I wipe / on every boot except for the files that I specify, and I backup /home to my NAS on ZFS and I backup my NAS snapshots to Backblaze.
Why do you wipe your root dir?

apt purge is calling and would like a word
