Great, thanks for the info, much appreciated!
Before I start doing any work on the image I would like to explain what I would like to achieve.
My current server is running 5.2 on xenon CPU with 16 GB of ram, 6Gb LSI HBA, this is so I can run few virtual machines using the VpirtualBox with php GUI package from http://spk.diablos-netzwerk.de/#showhistory_virtualbox. It works perfectly on 5.2 and I wanted to create a test bed so I can see how it works on 6.x before I move the whole system.
Unfortunately the latest supported version by the VirtualBox is DSM 6.0 7321. My aim was to edit VERSION file inside /etc/ folder so it lets me install the DSM_DS3615xs_7321.pat .
Is the loader going to work with 6.0 7321 at all or I should not waste my time and wait for release of the DSM source for the current versions?
I have already tested all the features from the 6.0.2 updat8 using your loader, the one I'm particularly interested in is btrfs, I was able to make snapshots send them over ssh to remote locations, run stuff directly off the remote snapshots it's just awesome. Been log wait to see zfs-like file-system on the Synology
