Your kernel does not appear to be compiled with support for unprivileged user 

namespaces (CONFIG_USER_NS=y), or something else is preventing creation of user 

namespaces. This feature is critical for sandboxing. Arch Linux is known to 

ship with a kernel that disables this feature; if you are using Arch, you will 

unfortunately need to compile your own kernel (see 

https://bugs.archlinux.org/task/36969).If you are not using Arch, and don't 

know why your system wouldn't have user namespaces, please file a bug against 

Sandstorm so we can figure out what happened.

 

.....anyone?  

 

 

Thanks!

 

(going to try compiling now, but figured I'd ask...)

In general:

 

If you need some particular feature in kernel and you are not in a rush, propose changes directly to kernel config @Github:

 

(Kernel) configurations:

kernel 4.0.5 config:
 

linux-sunxi-next.config

Igor,

 

This is just an FYI: 

 

Docker works on my BPI.  I am not sure why it does and sandstorm doesn't, and when I figure it out, I'll let you know.
