Subject: lm_sensors 2.8.2 / DESTDIR / root
The reason for this email is that I always try to avoid running
Makefiles as root, even during 'make install'. Therefore, I
always use the DESTDIR feature, when it's available. Until today,
I always built i2c and lm_sensors by doing
$ make
$ make -i install DESTDIR=/foo
$ cd /foo && su root && fix permissions/ownership && install
The -i flag to make install is a kludge to avoid having to be root
while installing to the DESTDIR, and it's only required because
the files are installed with "-o root -g root". Using the -i
flag is of course not a good idea, since more fatal errors can
easily fly by undetected.
Today, I upgraded to Linux 2.6.0, and tried a similar install
procedure for lm_sensors, except that the make target is now "user"
and the install target is "user_install". I now noticed that the
DESTDIR variable is not used everywhere in "user_install", so I
couldn't use the -i kludge anymore. Instead, I wrote a patch that
removes the "-o root -g root" arguments to install everywhere, and
I also tried to add DESTDIR to all files/directories installed.
(The patch only applies to lm_sensors, not i2c, since only
lm_sensors is required in Linux 2.6.0.)
There's really no reason to say -o root -g root anyway, since if you
do install directly with make install, you have to be logged in as
root, and then the files will get the right ownership by default.
Much of the point of installing to a temporary DESTDIR is that you
don't have to be root, and that you can prepare the installation
by hand. Fixing the ownership is trivial:
chown -R root.root $DESTDIR

/configure database based on detected/configured sensors,
logs libsensors-processed readings to the database, has a
command-line option for generating a basic rrdcgi script.
Removed sensord from all target because it has an external
dependency on librrd.
This just makes using RRD with sensors easier; you don't
need to figure out what sensors are available and configure
the database with computations that are already in
sensors.conf.
To install:
make install-prog-sensord
To create and start logging to database:
sensord --rrd-file /var/log/sensord.rrd
To create a CGI script:
sensord --rrd-file /var/log/sensord.rrd \
--rrd-cgi /var/www/sensord \
> /usr/lib/cgi-bin/sensord.cgi
man sensord for more details.
Kudos to Mark for doing the hard work ;}

ALERT so you can pick them up in syslog.conf and fire them to
the console, etc. Added support for scanning only for alarms
in addition to scanning regular values, etc. Updated the man
file to reflect the new options, etc. Operation as "sensors"
command is undocumented.

. added support for via686a and other new chips
. added support for alarms and beeps
. updated to log through syslog instead of a custom logfile
. updated so when run as "sensors" (ln -s sensord sensors) it
mimics the existing sensors command except for formatting
. modularized a bit
Yet to do:
. complete support for alarm checking without sensor logging
. signal alarms through syslog level ALERT
. add final support for multivalued alarms
. check up on some questions about existing sensors command
. update manual page inc. notes on syslog usage
. test more fully

Set DESTDIR if you want to install at some other place then where you
will run everything from.

default. Now uses libsensors. Ripped the display formatting code from
sensors (with some modification) but needless to say I've only tested
a single chip. Doesn't support alarms yet. With a bit of work, could
share the display formatting code with sensors so just one source needs
updating. Compiles on my machine.
