Yes indeed.  A distinguished colleague of mine has proposed the
following alternatives (see OMA-DM-DM13-2011-0029R02-
CR_Client_Initiated_Bootstrap_and_DM_Bootstrap_Discovery.zip):

1)  The host first obtains its domain name from the response that it
receives for a DHCP query that includes the "Client FQDN" option, with
an empty Domain Name field, as specified in [RFC 4702] and [RFC
4704].  It then issues a DNS Resource Record query, as specified in
[RFC 2782].

2)  The host first obtains its domain name from the response that it
receives for a DHCP query that includes the "Access Network Domain
Name" option, as specified in [RFC 5986].  It then issues a DNS
Resource Record query, as specified in [RFC 2782].

Thanks,
Choi
