Building and running btsync

[TheChymera]

Hey there - I am trying to write a package aton (an ebuikd, which actually contains build instructions) for btsync on Gentoo.

This is the relevant file if you're curious https://github.com/TheChymera/chymeric/blob/master/net-p2p/btsync/btsync-1.1.70.ebuild

In any case:

• I have noticed that the btsync archive just contains one file - If I try to run it (either after emerge or just directly after manually extracting it from the archive) it tells me it forks to the background - but I can get neither debugging output nor do I see a GUI.
  Like so: BitTorrent Sync forked to background. pid = 4597
• Does the package depend on bittorrent?
• The init.d scripts I found seem to be tested - but I use systemd. Can you give me any input on my btsync.service file? I never wrote one before.

Many Thanks
