Yes, that's right.  It's just like "dd iflag=noatime".  The general
rule is that dd issues a runtime diagnostic and immediately fails if
you try to use a flag that isn't supported on the current platform.

The issue is more complicated than "linux specific".  For example,
iflag=noatime is supported by some Linux kernels but not others.
And iflag=nolinks works on SunOS 5.10 and later, but not on any Linux
kernel that I know of (yet).
