sure it can be more convenient but I think I have to check all settings 
then at make sure they work for both applications. The man page for 
phc2sys has a quite clear warning about this, probably for a reason:

        WARNING
        Be cautious when the same configuration file is used for both 
ptp4l and phc2sys.  Keep  in
        mind,  that  values specified in the configuration file take 
precedence over their default
        values. If a certain option, which is common to ptp4l and 
phc2sys, is specified to a  non-
        default  value  in  the  configuration file (p.e., for ptp4l), 
then this non-default value
        applies also for phc2sys. This might be not what is expected.

        It is recommended to use seperate configuration files for ptp4l 
and phc2sys  in  order  to
        avoid any unexpected behavior.

But along the road when I get full control of the applications this can 
probably be a good solution.

Thanks,
