It's been a while since I bothered but IIRC I've been able to prevent the dialog by disabling one of the Apple-specific pool or dataset properties.
@RJVB Hi! I've found out that putting zfs.fs in /System/Library/Filesystems in 10.9 instead of /Library/Filesystems removes the warning message!
M. Lundman applied that fix in v2.2.2 (although he forgot to remove zfs.fs from /Library/Filesystems,
but it seems harmless to have both — I guess the one in S/L has precedence — but you can also manually remove it).
Apparently, the only issue remaining in 10.9 is when using an external USB drive, but otherwise all my tests went ok.
