Using: PrivateDevices=true DeviceAllow=char-ipmidev rw does not work. After further investigation I found that it is because in the new /dev mount created by PrivateDevices=true /dev/ipmi0 is missing. I did try with the line: DeviceAllow=/dev/ipmi0 rwm but still /dev/ipmi0 is missing from the /dev mount. Any suggestions?
