From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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

Random thoughts, no particular order

I think btrfs was the default the last time I installed Bazzite, but I don't really know anything about it so I switched it to ext4. I understand the snapshot ability is nice with rolling release distros, though.

It'd been ages since I'd used FAT32 for anything until I made a Debian live USB when I was setting up my pi-hole on an old Core2Duo recently. It would only boot on FAT32 for reasons I probably once knew. 😆

NTFS was an improvement over the FATs what with the journaling, security, file streams, etc. I use it wherever I still use Windows (work).

Most of my general purpose USB flash drives use exFAT. I like not having to worry about eject/unmount.

Sure.

Bazzite defaults to btrfs and yeah this distro with rolling back changes is on another level.

Well you probably used it if you had any brand new USB as it's the default. I'm trying to flash my USBs for now with exFAT or NTFS...

NTFS is like Windows - the necessity when nothing else will work.

Wait what. exFAT can make you not to worry about eject/umount?

I mainly started using exFAT on flash drives (even on new ones) since it is interoperable between Windows, Linux, and Intel Mac. To be clear, I never don't unmount the drive properly under normal conditions, but I remember reading around the time it was introduced that the Windows implementation guaranteed the buffers were flushed after every write (meaning no unwritten data remains when the activity indicator on the drive stops blinking) but now I can't find any evidence that was ever the case. Wouldn't be the first time I got bad info from the Internet. 🤷‍♂️
