openmoko-devel-image do_rootfs fails in makedevs

[jseghers@…]

This task first erases the old rootfs, creates rootfs/dev then calls makedevs.

However, the input file to makedevs also specifies three files in rootfs/bin
which it is unable to write because of the missing directory.

openembedded/classes/image.bbclass needs to create rootfs/bin before calling
makedevs

Error is shown below:

/home/moko2$ make openmoko-devel-image
( cd build && . ../setup-env && \

bitbake openmoko-devel-image )

This patch works, but is more a workaround. In the end makedevs should not
install binaries I think.

I added the information to a upstream bug as this is not an OpenMoko? only problem.
​http://bugs.openembedded.org/show_bug.cgi?id=2820

I leave this bug open until it gets upstream and we can use the fix.

Thanks for your report and time.

Richard Purdie fixed this in OE.dev now.
