# POSIX sh, not bash: this is piped into whatever /bin/sh happens to be, and a bashism
# here fails on exactly the minimal systems most likely to be running an agent.
#
# It verifies the checksum before installing. Piping a script from the internet into a
# shell already asks for trust; silently running an unverified binary afterwards would
# be asking twice.
