Yes it is quite intertsting then.
I am trying to implement the authentication with option 90 in the
As the things are going to be very dynamic , I don't think that the
server can assign any default value on them.
Therefore I was worried if the option 90 will come and if by chance the
server goes to the configuration file how it is going to react.
As this can break the functionality of option 90.

I just tried a configuration file without any "* lease-time" statements.
I checked lease file on the client
It shows

INTERFACE = "eth0"
It goes like this.
I think the dhcp server has some default value to send out incase if
that missing.
I hope somebody will explain the proper behaviour.
