That's the ENOSYS error code on Solaris.

I cannot reproduce this here because I don't have access to different
versions of Solaris. it would be interesting to see which particular
command fails with which options, and in particular, which are the
failing system calls. The tool for system call tracing on Solari sis
called "truss".

I can likely guess from the failing system calls.

We should be able to just make it work.

Thanks,
