apcupsd's ebuild (3.10.13 and 3.10.15-r1) configure the sbin directory to be in /usr/sbin rather than /sbin and loggging to be in /var/log rather than /etc/apcupsd. This is fine for normal operations, but when a power failure occurs and the ups batteries become exhasted, the killpower command can not be run if /usr and/or /var are separate mountpoints from root (/). Note that I have modifed /etc/init.d/halt.sh to include essentially the code in /etc/init.d/halt at the end of the file (after unmounting and remounting root read-only). Reproducible: Always Steps to Reproduce: 1. Configure drive partitions to have separate mount points for {/,/usr,/var} 2. emerge & configure apcupsd 3. unplug power from UPS, let batteries drain 4. When apcupsd shuts down the system /usr and /var are unmounted 5. code at end of halt.sh issues command `/etc/apcupsd/apccontrol killpower` 6. previous command tries to call `/usr/sbin/apcupsd --killpower` but /usr is no longer mounted. (and if you copy apcupsd to /sbin it will bomb out because it cannot log to /var/log/apcupsd.events). Actual Results: /usr/sbin/apcupsd does not exist (because /usr is not mounted). Results in UPS never being powered down. Expected Results: issued killpower command to UPS, resulting in UPS turning itself off.
If this problem still exists for apcupsd-3.10.18 then feel free to reopen this bug.

Still unfixed, reopen.

How did you modify the "halt.sh" script in order to mount readonly /usr? And what about the log file /var/log/apcupsd.events? Is there any problem with apcupsd if he cannot access it? Thanks.
Yeah, I just ran into this too. It seems like apcupsd is the kind of executable that should really be going into /sbin anyway... Seems like that'd be a pretty quick fix, and that seems to be the recommended installation method, a la: http://www.apcupsd.org/manual/Building_Installing_apcupsd.html#SECTION000115000000000000000
Well, looks like the most recent ~x86 (3.12.4) already does the install-to-/sbin trick, so I guess I'll just move to that instead of putting together a patch for this version.
It still doesn't work even with binary in /sbin, because it linked with libstdc++ (and one more library), which is located in (yeah, you guessed it) /usr. See bug #178931. I don't see any possible solution to be honest, cause you can't build apcupsd staticly, because it uses pthreads and you can't switch it off. Is there a way to staticly link only some libraries to executable? Anyway, there is a quick workaround: 1. mkdir /root/root ; mount --bind / /root/root 2. mkdir /root/root/usr/lib ; cp -a /usr/lib/gcc /root/root/usr/lib/ 3. umount /root/root ; rmdir /root/root Now it works fine, but it's not a real solution.
good news: apcupsd-3.14.2 no longer links to libstdc++ it does however link to libnetsnmp and libcrypt (both in /usr/lib), but only with certain configure arguments / use variables. setting USE="-snmp" (configure --disable-net-snmp) appears to remove this dependency and allow apcupsd to run with /usr unmounted, i.e. power-down the battery during shutdown. No alteration of halt.sh is required. I did not try EVERY combination of USE variables, so if you find a build parameter that links user libs again please post your results. I will attach the updated ebuild and new patch I used. Other patches are from 3.14.1 in portage.
