>> I defined an option space (dhcpd 4.1.1) that looks like this (sample):

>> option test.option130 code 130 = text;
>> When I now take a look at the dhcp packet the server sent out, the option 43 (vendor-encapsulated-options) includes all the values I assigned in that option space but not in the correct order. The order is: 1, 128, 130, 4, 5, 7, 8, 9 and not 1, 2, 4, 5, 7, 8, 9, 128, 130 (as I expected). Is this a bug or is there a way to define the order of the values within an option space (like dhcp-parameter-request-list)? Thanks in advance for your help.

No, the option names were just samples and it makes no difference if you change them. The sorting seems actually to be done by the option code but unfortunately not in the right way. I think an option like "parameter-request-list" for the options within an option space would be helpful.
