[Sync with official ubuntu packages but access/rights issues]

Hi,

I have installed Sync with the official ubuntu package

 

It starts correctly and I added the btsync user to the group that owns my data (with a usermod -a -G xxxx btsync)

 

But the files created are owned by btsync so my user xxxx has not any edit right on the files added by btsync

 

I tried to change the /etc/init.d/btsync script in order to change the btsync_user to xxxx, stopped and restarted the process but it is still a process launched by the user btsync and not xxxx

 

Did I miss something or a step ?

 

Thanks
