# 2021-08-04: Non-native systemd service 'asterisk.service' (redirects via
# systemd-sysv-install, to '/etc/init.d/asterisk status' etc) is Enabled but
# Not Active at this point.
# 2021-08-05: Asterisk's systemd / systemctl support is getting there but Very
# Imperfect (even when compiled in, as a result of package 'libsystemd-dev' at
# the top of asterisk.yml).
# 2021-08-12: Let's try to track the "official" init.d / update-rc.d
# instructions ('update-rc.d -f asterisk remove') but using systemd instead,
# to be more future-proof?
# 2023-04-02: Disagreement remains the same as 2 years ago:
# @jvonau wants to stop service asterisk (from the asterisk install).
# @holta prefers we track Asterisk/FreePBX community's mainline/consensus.
