pacman_rollback plans from the bus: each package now -> record from the node's cache, else the archive's
exact version, else the archive's repository on the record's date; added packages listed and removed only
when asked; foreign packages untouched. apply is an ask the node's keeper runs as a rollback run through the
root helper's new Rollback act (RootActs, upgrades.go), with rollback.started, rollback.finished and the
after-upgrade check (TakeAsk's rollback case, transaction.go).
At its start the keeper reads the log into runs once, prunes old records and carries unfinished runs on;
after every released lock it carries them on again; it takes each ask at <node>.* and prunes records daily.
The root helper's client is a constructor (newRootActs) the helper replaces; until then every act is
refused, named.
A fixture of pacman and checkupdates output holding command lines, environment variables and messages
leaves only names, versions and repositories in installed, updates and package.changed, and no command
the keeper runs names a package, a foreign one least of all.
pacman_packages answers one package on every node, or each node's counts, its explicit packages no module
declares and its foreign ones apart, the versions that differ and the packages on some nodes only, with a
node over the bus's cap marked not current. pacman_updates, pacman_installed and pacman_foreign read the
keeper's states instead of the machine; pacman_updates says when each node's list last changed.
A failed read keeps the last list and says reachable false, so a list the node can no longer confirm is
never shown as current, and a first read that fails is never an empty list taken for an answer.
The keeper reads pacman's database into installed.<node> and writes it only when it differs from the key,
says each change as package.changed, and keeps the last value when the list is over the bus's cap, marking
the node not current until it fits again; the health names the size. The loop runs over injected states,
events, clock, watch and machine, and leaves hooks (start, after a transaction, state watches, wakes) for the
upgrade parts of ADR 0508.
ADR 0508 §9 and §10: systemd-boot gets an entry from the booted command line, GRUB a regenerated menu only when its kernels change, a found kernel-copying hook is taken over, a full boot partition fails loudly.
The keeper process runs under its own account with a bus account of its own,
keeps the six states and emits the nine events of ADR 0507 and ADR 0508; its
config (upgrade-order, record-days, round-start-minutes) lands in its config
file and restarts it. shapes.go fixes every key's value and event body as the
interface the keeper and the verbs share. The weekly timer and its service are
dropped, which the node-engine removes.
