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.

There's been some Friday night kernel drama on the Linux kernel mailing list... Linus Torvalds has expressed regrets for merging the Bcachefs file-system and an ensuing back-and-forth between the file-system maintainer.

One of the best filesystem codebases out there. Really a top notch file system if you don't need to resize it once it's created. It is a write through, not copy on write, so some features such as snapshots are not possible using XFS. If you don't care about features found in btrfs, zfs or bcachefs, and you don't need to resize the partition after creating it, XFS is a solid and very fast choice.

Ext4 codebase is known to be very complex and some people say even scary. It just works because everybody's using it and bugs have been fixed years ago.

xfs_growfs is a thing. I know nothing about xfs. Is this something I should avoid for some reason?

No reason to avoid it. Just know that you can't easily shink the filesystem, only grow it. To shrink you'd need to create a new FS then copy the data over manually.

I heard that ext4s best feature was its fsck utils being extremely robust and able to recover from a lot of problems. Which does not shine a great light on the filesystem itself :/ and probably a result of the complex codebase.
