Oh it is actually pretty simple, it fails when doing some extra dd magic
on the final ext4 image:

/home/linus/src/openwrt/staging_dir/host/bin/make_ext4fs -l 536870912
-b 4096 -m 0 -J -T 1516271982

count=1
dd: failed to open
'/home/linus/src/openwrt/bin/targets/gemini/raidsonic/openwrt-gemini-raidsonic-ext4.img':
No such file or directory

The rootfs image
/home/linus/src/openwrt/bin/targets/gemini/raidsonic/openwrt-gemini-raidsonic-ext4.img
is not there.

However I guess it is looking for:
/home/linus/src/openwrt/build_dir/target-arm_fa526_musl_eabi/linux-gemini_raidsonic/root.ext4
that was just created in the step before by make_ext4fs?

I just don't find my way around the openwrt build scripts well enough to
figure out how to fix this...

However the rootfs per se is finished and is in
/home/linus/src/openwrt/bin/targets/gemini/raidsonic/openwrt-gemini-raidsonic-default-rootfs.tar.gz
so I'm using that (just untar it on the root partition) and it "should work".
However it is a bit reluctant to boot...

Yours,
Linus Walleij
