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.

Yes, its going to be similar to a .dmg file on the Mac.

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 kernel is built with the NTFS3 driver, provided by Paragon.

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.

AFAIK that's an incorrect meme that just won't die. The performance issues you're thinking of have nothing to do with the filesystem itself, but with the I/O subsystem in Windows more generally. If you have evidence otherwise please share.

A filesystem is not a disk image.

If it quaks like a disk image, it is a disk image

A filesystem is not a file.

(Yes, you can store a filesystem in a file - and that's a trivial sort of disk image, but one with some serious drawbacks like "you have to allocate all of the space up front". We can do better.)

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…

Not this kind of disk image. ASIF is a read-write disk image; an OS update would be distributed in a read-only image (if it is indeed a disk image).

Nice. But I would like it better if the effort was to support ext4, BtrFS, NTFS and other popular filesystems from the Linux and Windows world...

ext4 and Btrfs are only well supported on Linux; they are not universal standards. NTFS was only supported well on Windows until recently; but extensions like NTFS Encryption (BitLocker) are still Windows only. Mac still does not let you write to an NTFS volume. APFS and HFS+ are obviously Apple file systems. FreeBSD does not support ext4 or Btrfs well; but instead prefers UFS2 or ZFS despite also being an open-sourc…

> NTFS was only supported well on Windows until recently

I remember using ntfs-3g without any issues on my first Linux laptop 15 years ago. So that's not really "recently".
