UFS or ffs implementations have differences, which may be the reason why Linux
support is read-only and there is no support in Haiku.
I found, a few years back, that FreeBSD and NetBSD could not mount a DragonFly
BSD partition, and DragonFly BSD (using downloaded image written to USB stick)
couldn't mount a NetBSD or FreeBSD partition. Last time I downloaded a
DragonFly image to write to USB stick, it hung on boot.

I looked using ls -la /<mount-point> and ls -la /<mount-point>/root and found
no .attribute subdirectory. I ran dumpfs to verify whether the file system was
UFS1 or UFS2.
Subject did not appear on my last post because of either a mouse copy-and-paste

appeared as

I also corrected my email address, looked for and fixed other occurrences of
"mueller6726".
