Netbooting an old Netra X1

  In doing more web searching, I see that this error is one that has come up due to
ZFS changes to mountroot, so I thought I should include freebsd-fs in my inquiry.
I have a sparc64 Netra X1 tftploading the loader, kernel, and modules.  My intent
is to netboot it to install into a ZFS pool onto it's discs (It has no optical drive, and
no ability to boot from USB).

  As I noted to freebsd-sparc64, even when I set 

vfs.root.mountfrom="nfs:206.138.151.36:/data/nfs-exports/sparc64-freebsd9"

  in my /boot/loader.conf on the tftp server, The only result I get is the issue above,
where it seems to be looking at [], and failing with error 19.  Is error 19 specific
to ZFS changes, or very generic within mountroot, and only means what I'd already
feared, that it's simply failing to make the network connection?

  Just an inquiry.  Won't pester freebsd-fs unless there's a reason to think it might
be related to ZFS.  Was hard to tell from mailing list archives where there were
many comments that the "error 19" was new to some ZFS changes.

  Thanks.
