# A script to help with haproxy reloads. Needs sudo for :80. Running it for the
# first time starts haproxy, each subsequent invocation will perform a
# soft-reload.
# Receives /path/to/haproxy.cfg as the first parameter
# HAProxy options:
# -f config file
# -p pid file
# -D run as daemon
# -sf soft reload, wait for pids to finish handling requests
# send pids a resume signal if reload of new config fails
