# This sends all output from the command to journalctl while allowing CodeDeploy
# agent to capture it as well. It also prefixes the output with timestamps for
# better debugging via CodeDeploy logs.
#
# TODO Consider changing codedeploy-agent to do these things itself.
#
# NOTE Not POSIX compliant; must run in bash or bash masquerading as sh.
# TODO Figure out why codedeploy-agent (using Open3), isn't respecting the
# shebang to all our scripts which are /bin/bash. See:
