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 don’t really understand why the linux community complains about the licencing. I’m sure openzfs overcame that. In the freebsd world it’s native on root straight out of the box
Yeah there’s no essential problems with it in itself as free open source software. Legally it doesn’t seem compatible with the Linux kernel source code, as in you can’t compile it into the kernel but it seems to be okay to load it as a binary module, prebuilt or built on demand.
Yet practically no distros support it out of the box
And on root? Can practically forget it
Sad
Well Ubuntu is the most popular distro and it supports it out of the box. It’s had experimental ZFS-on-root support since 2020. Unfortunately it needs more work to be to be promoted from experimental status. But yeah, I don’t know of any other diatros supporting it on root out of the box. Which is sad.
