Sorry - I don't believe we have a maintainer for the ev3 build. I plan to work on it some on the first week in December, though.

My suspicion is that the issue is this one: mobileoverlord/nerves_system_linkit#3 (comment). For now, if you could add the symlink, I think that it will work. This can be done in the nerves_ev3_example's rootfs-additions directory so that you don't have to deal with the system image.

Fixed in nerves-project/nerves_system_br@1b7536c. It turned out to be a musl C library/Buildroot issue.
