Hi, freeipmi.conf could contain sensitive informations, default permission setted to it by build (in etc/Makefile.am) is 644, debian decreased it in packaging after build very long time ago (https://salsa.debian.org/debian/freeipmi/-/blob/master/debian/rules).
I think is good decrease it also upstream from 644 to 640 (removing read permission to others). Thanks for any reply and sorry for my bad english.
