Possibly it would be worth suggesting this to @vermaden for https://github.com/vermaden/automount?

[vermaden]

I do not have access to Apple hardware so I am not able to create APFS device for tests but ... can someone just format 4GB or 8GB USB pendrive using APFS, then create its image with dd(8) and sent it to me?

This way I can move that image to my USB pendrive and make the tests and add APFS to automount.

... or its possible to create APFS with the tools mentioned on FreeBSD?

Regards.

Thanks @vermaden, excellent. As I refuse to run any OS X later than 10.9 which does not use APFS, I cannot make an APFS dd gzip, but maybe one of our users interested in apfs compatibility can do that.

Thank you very much.

Thank You.

Will try to get into it this weekend or earlier :)

sgan81/apfs-fuse#139 by @johnothwolo is adding FreeBSD support to apfs-fuse.

Not sure if that helps but ...

Although I am not sure I imagine that the dmg was made by the Mac's Disk Utility which usually does not produce "raw" images (like dd would) of a disk but also puts a partition table and possibly additional partitions into the image. md0p2 does look like it is recognized as APFS by file -s, so it is probably what should be mounted. I don't know why doas /usr/local/bin/fsapfsmount /dev/md0p2 /mnt/tmp fails but possibly it would be worthwhile to try sgan81/apfs-fuse#139 on it.

I did use dd though

Ah, good to know, thanks.
