##### Attention! Please read carefully before you decide to use this image #####

- For development on a SCU which is located outside of GSI currently there is no solution available which is supported by IN

- Debian is not supported by IN ! It will react in a different way and is not binary compartible. So first do your development on asl cluster and only port it to Debian later. Be aware that the timing behavior will be different!

- There is as well the possibility to use IN.DosPendrive in combination with a CentOS Laptop for external development. However due to a lack of manpower, as well Laptops cannot be supported by IN. You have to install and maintain the OS and all required tools on your own

- In the past there was a proposal by IN to maintain an official SCU image with runs developer tools, however so far this proposal was not agreed on by staff.
