Package: nut
Version: 2.7.2-4
Severity: important
The POWEROFF_WAIT option in nut.conf does not work (has no effect).
I have a suspicion that it has something to do with systemd handling
system shutdowns nowadays, though it's too complex for me to investigate
further and find any proof (other than /sbin/shutdown and /sbin/poweroff
pointing to /bin/systemctl, which does not prove anything).
This bug introduces quite a regression I believe is worth fixing in
Jessie (even if it turns out to be fixed in later versions). Also, it
becomes especially hilarious together with #835555 - nut also doesn't
send the command to kill the power; so nut doesn't handle the case when
your UPS supports cutting the power, AND it doesn't handle the situation
when it does not. Seriously, did no one notice a 100% broken package
BEFORE shipping Jessie?.. A package that manages power supply, of all
things. Hence the "important" severity.
Details:
If the command for the UPS to kill the power is sent when AC power is
already back, my UPS ignores it. (And it's APC, so I really didn't
expect that kind of thing from them.) So, there is a risk to have all my
machines require a manual restart after a power failure.
And nut has a workaround just for this case...
Actions required:
- Add "POWEROFF_WAIT=15m" line in /etc/nut/nut.conf
Intended behaviour:
- After an emergency shutdown triggerd by NUT, the system is not
powered down, only halted. After a timeout (15 minutes in this
example) it reboots, in case the UPS did not cut the power
for some reason.
Actual behaviour:
- The system is always powered off, ignoring the option added.
Minor notes:
- man nut.conf has a section about this option which directs me to
/usr/share/doc/nut/docs/shutdown.txt.gz , which is not there anymore.
- man nut.conf does say that "if you want to specify time in seconds,
use the 's' suffix", but it does not say which suffix should I use if I
do NOT want to specify time in seconds. According to the example below,
using "m" is also possible - apparently, for minutes, but I was
wondering if "m" is already deprecated (along with shutdown.txt.gz
mentioned above) and I should use no suffix by default... I don't want
to do a real power failure test again just to find out.
