excerpt from Ian Smith:

There might be differences resulting in incompatibility between the versions of UFS in various BSDs, and Mac OS main filesystem is HFS+.

I noticed, after downloading DragonFlyBSD installation image, dd'ing to USB stick, and booting, it could read GPT partition table but was unable to mount any FreeBSD and NetBSD partitions.

Last DragonFlyBSD image I downloaded and dd'ed to USB stick didn't even get through the boot.

FreeBSD and NetBSD were unable to mount the DragonFly USB-stick partition.

There is also the issue of BSD disklabels when using MBR, and one BSD not being able to read the other's disklabel.
