Log from program watching changes to /etc/ directory

In the last reproduction attempt, I have also run a program that watches all
the changes in /etc directory (through inotify). There you can see that
apparently NM has created its resolv.conf version (resolv.conf.tmp) at 14:52:25
and moved it to resolv.conf in the same second. At 14:52:26, netconfig has
created its version of resolv.conf (resolv.conf.gANX1c - the attempts from NM
and from netconfig can be recognized by a different name of the temporary file)
and then at 14:52:27 renamed it to resolv.conf.netconfig because resolv.conf
was already modified by NM.
