Yohoo! Well, slightly off-topic now.
It is a Debian derivative. Univention Corporate Server. uname -r says: 4.1.0-ucs190-amd64 So I am pretty fine with the kernel. But indeed, I have to think about getting a more up-to-date btrfs as I ran on resizing in the "File too large" issue so I had to use "max" instead of "+100G". No big deal, just a minor issue. I use btrfs to checksum all files stored there as I had several issues the last years where files got corrupted.
