I'm still looking for a widely supported (at least FreeBSD and Linux kernels) filesystem for external drives to carry around that doesn't have the FAT32 limitations. There's exFAT but no stable and supported implementation. Then there's NTFS, but that's also not 100% reliable in my experience when used through FUSE (NTFS-3G). I've considered UFS but that also was a no go. I'm hopeful for lklfuse[1] that also runs on FreeBSD and givess access to ext4, xfs, etc. in a way like Rump and allows you to use the same drivers on FreeBSD. I'm cautious though, given that I don't want corrupted data I might notice too late. Let's see if lklfuse provides LUKS as well, otherwise Dragonfly's LUKS implementation might need to be ported to FreeBSD or something like that. External drives one might lose need to be encrypted.
Thanks for this! I didn't realize (or had forgotten) LUKS had been ported to Dragonfly. Also you touch upon my #1 frustration with APFS without really knowing anything about it: simple portability.
