/*
Debootstrap Action
Construct the target rootfs with debootstrap tool.
Yaml syntax:
- action: debootstrap
mirror: URL
suite: "name"
components: <list of components>
variant: "name"
keyring-package:
Mandatory properties:
- suite -- release code name or symbolic name (e.g. "stable")
Optional properties:
- mirror -- URL with Debian-compatible repository
- variant -- name of the bootstrap script variant to use
- components -- list of components to use for packages selection.
Example:
components: [ main, contrib ]
- keyring-package -- keyring for packages validation. Currently ignored.
- merged-usr -- use merged '/usr' filesystem, true by default.
