I see that bugs.debian.org says this bug is "No longer marked as found in versions sysvinit/2.86.ds1-61."
However, the bug is still present in sysvinit 2.88 as can be seen from: https://sources.debian.org/src/sysvinit/2.88dsf-59.10/src/shutdown.c/#L518 case 'P': halttype = "POWERDOWN"; and: https://sources.debian.org/src/sysvinit/2.88dsf-59.10/man/shutdown.8/#L174 \fIINIT_HALT\fP to \fIHALT\fP, and the \fB-P\fP option just sets that variable to \fIPOWEROFF\fP. The shutdown script that calls I believe the severity of this bug should be increased, as it can cause loss of service when a UPS is involved. This is because if UPS software is configured to execute "shutdown -hP now" when the battery level becomes critically low, /etc/init.d/halt powers off the system without invoking "/etc/init.d/ups-monitor poweroff" to tell the UPS to kill the power. If A/C power is restored before the UPS turns itself off (which is likely, as the UPS now has no load) the system does not get restarted and has to be powered up manually. Of course the simple work-around for this problem is to configure "shutdown -h now" instead of "shutdown -hP now", but fixing the bug in shutdown.c would prevent it happening to admins who are not (yet) aware of it and who are misled by the man page into thinking that specifying -P would be prudent to ensure poweroff. Please change: halttype = "POWERDOWN"; to: halttype = "POWEROFF"; ASAP.
