Hi,
I noticed that there's a problem when you start radiator for the
first time (i.e. with nonexistent logfile) and User is set to some
non-root user. The logfile is created when radiator is still running
as root (at least when debug log is enabled), so it's not writable
anymore for the radiator process after the effective user id has
been changed.
What I did to fix it:
