As operações pontuais de um container de sistema: snapshots.

The one-off operations of a system container: snapshots.

Um container de sistema (kind: SystemContainer, ADR-0058) é criado, mudado e apagado por manifesto. Este grupo tem o que um manifesto não consegue dizer: snapshot create|ls|rm|restore, os mesmos quatro verbos do vm snapshot. Um snapshot é só do volume raiz — um container não tem estado de memória a guardar. Um restore deixa o container como estava antes: a correr se estava a correr (o nó pára-o para o rollback e o motor espera que volte a responder), parado se estava parado. O que o rollback mudou aparece no plan seguinte como deriva face ao manifesto. Não estável — ver docs/cli-stability.md.

A system container (kind: SystemContainer, ADR-0058) is created, changed and deleted by manifest. This group holds what a manifest cannot say: snapshot create|ls|rm|restore, the same four verbs as vm snapshot. A snapshot is of the root volume only — a container has no memory state to keep. A restore leaves the container as it was before: running if it was running (the node stops it for the rollback and the engine waits for it to answer again), stopped if it was stopped. What the rollback changed shows in the next plan as drift from the manifest. Not stable — see docs/cli-stability.md.
