//! Startup milestones reported out of [`Runtime::init`](crate::Runtime::init).

/// A milestone [`Runtime::init`](crate::Runtime::init) passes while bringing
/// the System VM up.
///
/// `init` is a single call spanning the slowest stretch of daemon startup:
/// staging the guest runtime binaries, booting the VM, the agent handshake,
/// then probing the guest container runtime. A caller that wants to report
/// progress to its own clients needs the boundaries *inside* that call, and
/// cannot recover them from call order — doing so would bill the binary
/// download to VM boot and could not separate "the agent answered" from
/// "dockerd answered".
///
/// Reported on the calling task, in declaration order, and only while a
/// System VM is actually coming up: VM-host-only mode (`vm.autostart =
/// false`) starts no VM and reports nothing.
