manta-cli 2.0.0-beta.67

//! Implements the `manta apply boot nodes` command.
//!
//! Applies a boot configuration (image id, runtime configuration,
//! kernel parameters) to nodes selected by a hosts expression via
//! `POST /api/v2/boot-config`. Sibling of [`super::boot_group`] which
//! takes a group name and resolves the members first; both leaves
//! forward the request's `dry_run` flag verbatim to the server.
