const CleanShutdownService = "" /* 238 byte string literal not displayed */

CleanShutdownService is added to machines to ensure DHCP-assigned IP addresses are released on shutdown, reboot, or halt. See bug http://pad.lv/1348663 for more info.

const CleanShutdownServicePath = "/etc/systemd/system/juju-clean-shutdown.service"

CleanShutdownServicePath is the full file path where CleanShutdownService is created.

func UnitSerialize Uses

func UnitSerialize(opts []*unit.UnitOption) io.Reader

UnitSerialize encodes all of the given UnitOption objects into a unit file. Renamed from Serialize from github.com/coreos/go-systemd/unit so as to not conflict with the exported internal function in export_test.go.
