xfce4-sensors has hddtemp support. By default, SUID bit on /usr/sbin/hddtemp is off: neptune / # ls -l /usr/sbin/hddtemp -rwxr-xr-x 1 root root 35896 Jun 3 19:23 /usr/sbin/hddtemp and xfce4-sensors notifies that it cannot run hddtemp - (and one can chmod u+s hddtemp to solve it) and continues to work normally. But if SUID bit is on, xfce4-sensors crashes on launch (see below at "additional information"): neptune / # chmod u+s /usr/sbin/hddtemp && ls -l /usr/sbin/hddtemp -rwsr-xr-x 1 root root 35896 Jun 3 19:23 /usr/sbin/hddtemp hddtemp works normally itself: neptune / # hddtemp /dev/sd[a.b] /dev/sda: WDC WD2500KS-00MJB0: 54 C /dev/sdb: ST3750640AS: 52 C Reproducible: Always Steps to Reproduce: 1. USE="acpi hddtemp lm_sensors" emerge xfce4-sensors 2. chmod u+s /usr/sbin/hddtemp 3. run xfce4-sensors - it will crash Actual Results: xfce4-sensors crashes Expected Results: It should work normally
