Title:
  missing DOMAINSEARCH in initramfs output files if the DHCP server
  doesn't provide one

Status in isc-dhcp package in Ubuntu:
  Fix Released
Status in isc-dhcp source package in Xenial:
  In Progress
Status in isc-dhcp source package in Zesty:
  Fix Committed

Bug description:
  For networked systems, for instance booting with an iSCSI root,
  dhclient writes an output file in the form of /run/net-<iface>.conf
  that contains data for other programs to consume. This allows, for
  instance, open-iscsi to get the right information and properly connect
  to the server to mount the root filesystem.

  It is common for DHCP servers to only provide a domain name value, and
  no search domains. In this case, isc-dhcp doesn't currently write
  DOMAINSEARCH, but people may wish to use short names to resolve things
  (such as in iSCSI server).

  In the not-initramfs dhclient-script, when domain_search isn't
  provided but domain_name is, domain_name is written to the search
  string. If both are provided, domain_search is written. The initramfs
  enter hook should do the same.
