*Some* clients may interpret the option that way, but it is not
guaranteed behaviour, and I do not think it is RFC compliant.
A later RFC introduced the domain-search option which does exactly what
option domain-search domain-list;
The domain-search option specifies a 'search list' of
Domain Names to be used by the client to locate not-
fully-qualified domain names. The difference between this
option and historic use of the domain-name option for the
same ends is that this option is encoded in RFC1035
compressed labels on the wire. For example:
option domain-search "example.com", "sales.example.com",
