  That's good.

  That's good.

  Hmm... I'm a little more unsure about that.

  That's better.

  I dislike what?

> There's also a new xlat expansion %{dhcp_options:}. Some switch vendors offer DHCP to RADIUS gateways, but don't define their own VSAs to represent DHCP options, so include the DHCP options from the DHCP packet as an opaque blob of binary data packed into a single VSA.

  That's good.

> Seeing as the server already has the code to parse dhcp options, it seemed like a fun hack to expose it as an xlat function. %{dhcp_options:} takes an attribute reference with qualifiers, and expands to the number of options in the blob. During expansion it adds all the options it finds in the blob to the request list with +=, using the FR DHCP dictionary.

  There's an RFC I keep meaning to write about that.
