[Nut-upsuser] nut UPS kill inverter: offdelay ignored

Dear All,

I am running Slackware64-14.1(Linux marto 3.10.17 #1 SMP Fri Feb 14 16:39:21 CST 2014 x86_64 Intel(R) Pentium(R) CPU G3250 @ 3.20GHz GenuineIntel GNU/Linux)
with kernel 3.10.17 and nut package nut-2.6.5-x86_64-1_SBo, buit from source using the build script http://slackbuilds.org/repository/14.1/system/nut/

In the README.Slackware it is suggested that
the commands for killing the inverter be placed in certain positions in rc.6 after remounting the root
file system read only. In my configuration, however, the /usr and /root directories are on
different partitions, so I added these commands after turning off swap and before unmounting the
local file systems, like this:
# rc.6
# Turn off swap:
echo "Turning off swap."
/sbin/swapoff -a

# Turn off UPS's power
if [ -x /usr/libexec/nut/nut_restart_udev ]; then
 . /usr/libexec/nut/nut_restart_udev
if [ -x /usr/libexec/nut/nut_kill_inverter ]; then
. /usr/libexec/nut/nut_kill_inverter

echo "Unmounting local file systems."
/bin/umount -v -a -t no,proc,sysfs

I also set in the ups.conf file that the UPS should be killed 3 minutes after issuing the kill
inverter command:
# ups.conf
driver = usbhid-ups
port = auto
desc = "UPS Eaton5E650iUSBDIN"

On power failure the shutdown process reaches the kill inverter commands in rc.6,
issues them and in several seconds shuts down the UPS, obviously ignoring the offdelay setting.
Furthermore, it does not proceed to issue the remaining rc.6 commands, but seems to hang at shutting down the UPS.

Do You have any suggestions?

Thank You very much for Your attention.

Best regards,
