Thanks again for assistance, the initimage works flawless now and i’m stoked to start trying to build my own tools into it.
I ran into another problem with 0x0000007b and fixed the IDE-Drivers used in my virtualbox-installation to the generic ones.
The inotify_add_watch error cleared itself mostly, no such errors during upload, 1 error during download but the deployed image boots without problems.
So thanks again, i’ll start using this software on a larger scale and i hope i can be of assistance in the future.
