Hello Fabian, I'll look at that one, there also seems to be a confix.txt in /boot, that the RPI uses for several things. What I noticed though, is that if there's no cfg script in network-scripts for the device (ifcfg-wlan0), after NetworkManager starts, the Mac addr seems to be random. (while on other Centos/RHEL/etc machines I have, in that case the Mac address/device would just not show. When that script is there, NetworkManager consistenly shows the correct Mac (which depends on the serial of the board, I read somewhere) thanks, Ron On Tue, Apr 3, 2018 at 1:37 AM, Fabian Arrotin <arrfab at centos.org> wrote: > On 02/04/18 04:19, cjvijf at gmail.com wrote: > > Hello, > > > > > > I don't know if this is a dev issue/problem, but I bought 2 RPI 3 about > > a year ago, and installed centos on one (the other one I haven't even > > used yet). > > > > It seems the Mac address changes every reboot?
