Problems setting up dhcpv6 option 59 (boot file name -- rfc5970) on bind10

[Angelo Failla]

Hello Marcin,

Thanks for your response, I don’t have an account yet. Can you submit the
bug report for me?
Is there any work around this in the meantime?

Can I define option 59 as a member of the vendor-opts-space?
