Nut upsuser - Aug 2013 - APC Back-UPS CS and ES series

I'm using FreeNAS 9.1, and I've just got an APC Back-UPS CS 500. In
theory it's supported by NUT, but the latest released version (2.6.5)
doesn't have support for it (the driver reports an error, which is
apparently due to an overflow). According to a thread on the mailing list,
Back-UPS ES series requires a fix that's in source control, and CS series
requires an additional patch:

I'm happy to test an updated build, but have no idea about how to go about
doing a build in the first place. Could someone help me in the process of
creating a snapshot build for FreeNAS?

I am not familiar with the specifics of building for FreeNAS, but our BuildBot
instance is making source snapshots again:

   http://buildbot.networkupstools.org/public/nut/waterfall?show=Debian-x64-gcc

On the "Uploading..." step, there is currently a link to
nut-2.7.1-pre1.tar.gz - that can be built just like 2.6.5.

Somewhere in the FreeNAS source is the command line that you would use to
configure NUT to put all of its binaries in the same place that FreeNAS does.
Someone asked for that in the second forum link, but there wasn't an answer
in that thread. I also didn't see that in a quick search of the NUT archives
(we've done this a few times to test out similar in-place upgrades in
Linux.)

I think I see where FreeNAS is getting their copy of NUT. They use a ports tree,
so I tried building the latest NUT tarball in /usr/ports/sysutils/nut on a
FreeBSD 9.1 box (in place of 2.6.5).

   http://www.freshports.org/sysutils/nut/

The port build system doesn't like our intermediate version number
(2.7.1-pre1), so I hacked that to be 2.7.0. There are also some patches which
don't apply, so I blindly removed them. I suspect they will need to be
regenerated by the port maintainer.

None of this should stop you from building a copy of just one driver, and
copying it over the 2.6.5 driver. (The version number doesn't matter there.)

I haven't tried this in my FreeNAS VM yet, but I think you can download the
snapshot (see buildbot URL above), and configure it like so:

   ./configure --sysconfdir=/usr/local/etc/nut --program-transform-name= \
     --localstatedir=/var/db/nut --datadir=/usr/local/etc/nut \
     --with-drvpath=/usr/local/libexec/nut --with-statepath=/var/db/nut \
     --with-altpidpath=/var/db/nut --with-pidpath=/var/db/nut \
     --with-pkgconfig-dir=/usr/local/libdata/pkgconfig \
     --with-user=uucp --with-group=uucp --with-dev --without-cgi \
     --with-drivers=usbhid-ups \
     --prefix=/usr/local --mandir=/usr/local/man --infodir=/usr/local/info/ \
     --build=amd64-portbld-freebsd9.1

Then "cd drivers; make usbhid-ups", and copy usbhid-ups to
/usr/local/libexec/nut
