Previously we sourced this script in tests/deploy.sh, but this was
recently changed. Following that change we lost the errexit setting,
meaning we ignore errors in init-runonce.
Adding errexit in the script itself means that all callers get error
handling.
Also log init-runonce output.
Adapted to log stderr too (&>).
TrivialFix
