Yikes.  Are you sure you don't want interim (or 'none')?

That's not how it's supposed to work.

We need to improve our documentation.  I see how you got to there from
the manpage, but 'string' doesn't mean "hi!" it means 'a string of
octets' like de:ad:be:ef or something.  But that's not even what you
want either, what you want is to configure an option space for your
vendor (per their documentation).  Here's what our test config does:

  # Declare the option space.
  option space docsis code width 2 length width 2;

  # Anchor the docsis option space under the VSIO option.
  option vsio.docsis code 4491 = encapsulate docsis;

  # Define DOCSIS option formats.
  option docsis.tftp-servers		     code 32 = array of ip6-address;
  option docsis.cablelabs-configuration-file code 33 = text;
  option docsis.cablelabs-syslog-servers     code 34 = array of ip6-address;
  option docsis.device-id		     code 36 = string;

Then configure values inside the docsis space:

  option docsis.tftp-servers 3ffe:cccc:aaaa:aaaa::1, 3ffe:cccc:aaaa:aaaa::2;

It's similar to the 'vendor encapsulated options' section in
'man dhcp-options', but you're using the vsio space instead.  If
you give that a read it might make stuff more clear.

Anyway, I'll go write some better documentation on this for the next
release.  We should have some VSIO examples.
