Public bug reported:
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.
