smart_ now wants smartpath to find smartctl (an alternative would be to modify the plugin to look in the right place by default). Also, the sample config runs it in group operator but this is not sufficient without modifying the permissions for all disk devices and xpt0. I changed it to run it as root.

ipmi_sensor_ does not use an explicit path for ipmitool which causes problems because (apparently) /usr/local/bin isn’t in the default munin path. Modifying the plugin to use /usr/local/bin/ipmitool makes it work. It also seems to invert the limits for fans which cause problems so I reverted that change.

The sample config file nut has a trailing “ for env.upsconf which causes it to fail.

Also, sendmail_mailtraffic doesn’t work unless you have 'group wheel’ so it can read /var/log/sendmail.st
