#
# A shell script to command UPSes to disable delayed power off of outlet
# groups, which could have ben requested as part of the emergency shutdown
# driven by IPP - Unix (NUT); called from nut init-script
#
# Requires configuration from ipp.conf, or otherwise default to the values below
# Also requires matching features to be available in the UPSes and their drivers
#
# TODO remaining per IPSSUNIX-29:
# * Mismatch against the `shutdown` script: during shutdown we set
# `load.on.delay` and `load.off.delay` via `upscmd` for the UPS itself,
# as well as `upsrw` the similar settings for outlet groups, but during
# the `init` we reset to `-1` only the outlet group settings and not
# those of the UPS itself
# * The script acts on ALL UPSes configured on this system (`upsc -l`),
# rather than those MONITORed as feeding a non-zero amount
# power-sources in `upsmon.conf`
# * The username is hardcoded as `admin` rather than taken from config
# * Maybe we do not try every possible instcmd for UPS poweroff/reboot -
# revise against upsrw and upscmd for NETXML and SNMP drivers at least
