Sorry, one more corner case...

If I set a new profile then do a warm start without saving the
configuration, the system will come up with the new profile but the
configuration is still the old one. Furthermore I will not be able to
activate the old profile because freerouter thinks it didn't change.

So, I've removed "sticky-onlychanged" and "sticky-persistent" and this
is what I get for the various cases:

1) First boot after an installation (file /etc/freertr/p4-profile
doesn't exist)

I think this is only flagged as an error because the command produces
an output. But I think this is acceptable since it indicates that
something is not as expected (the profile in the p4-profile file is
different from what's in the configuration).

A regular boot has a clean log (that's case 2).

The only thing not so nice is that if you set the profile to what it
already is, the processes are restarted

I can't change that without messing up the boot log, but I guess we
can live with that.

Unless you disagree I'll leave it like this.
