Is there a single filesystem in the world (besides "simple" ones like FAT) that both has an open standard AND is licensed in a "usable" codebase (MIT or other "non-copyleft" license)?

zfs?

3rd party supporting a file system would be one of the last things on a list of all software I’d ever want a 3rd party writing instead of the OS maker. Nightmare to evaluate the options, pure stress testing the options, difficult to know if it didn’t mess something up.

Question, who maintains NTFS support for Linux? Microsoft? The kernel? The distros? Genuinely asking.

The current ntfs3 driver is developed by a company called Paragon, and it's been part of the kernel since 5.15 or so.

I was going to add some additional comments about this, but then I found that Paragon's website has an FAQ that covers everything I was going to say (and more): https://www.paragon-software.com/us/home/ntfs3-driver-faq/

correct. but it's also a management system so perhaps they only want a files system? no idea why more don't use zfs. especially after the auto expansion update earlier in the year.

I think UDF was meant to be this, though I don't think it supports everything you'd want. Does NTFS have licensing issues though?

NTFS has serious performance issues, nobody should use it.

xfs.

if GPL is a non-starter for you, youre missing the point of the open standard. apple already discloses a litany of various GPL it ships. XFS would be no different.

Any chance this will reduce the space needed for major OS updates? Those have always been desperately inefficient.

No. Disk images aren't involved in the OS update process.

They are - in that OS updates are delivered in and extracted from disk images. Not sure how they could be any more involved…

This article describes a new disk image format (on which a filesystem can be put, APFS in the article), not a filesystem, or did I misunderstand? edit: added the word "image", which I apparently forgot to type. Mentioning the edition because otherwise it would make an answer to this comment difficult to understand.

This is a new disk image format. Not even a disk format. For virtualizing a disk. On which you can put a filesystem, yes. There seems to be an extraordinary amount of confusion in many of the comments, I don't know why.

We really don't have enough disk formats in this space. Is this bringing something new ? Or is just polluting the namespace.

Apple recently made FSKit a supported/documented API, which should allow third-parties to add support for other filesystems: https://developer.apple.com/documentation/fskit?language=obj...

Just reading the title, I was like, I hope it is an update to encrypted sparse bundles, and it is.
