There is no kernel image in boot directory for edgerouter rootfs

There is only an empty symbolic link, no kernel image. This issue doesn't exist in MPC8315e and beaglebone.

The kernel is likely stored elsewhere so we perhaps just need to clean up the symlink?

It's better to put the real kernel image in the directory and keep the symlink like other BSPs' rootfs:

MPC8315:
$ ls -l boot/
total 5212
lrwxrwxrwx 1 root root      34 Jul 10 19:25 uImage -> /boot/uImage-3.19.5-yocto-standard
-rw-r--r-- 1 root root 5335431 Jul 10 08:57 uImage-3.19.5-yocto-standard
Comment 3 Kevin Hao 2015-09-15 03:27:29 UTC 
Fix by commit a346a3cd5273 ("kernel.bbclass: add the runtime dependency on kernel-vmlinux for kernel-image")
Comment 4 Ke Zou 2015-09-21 08:36:27 UTC 
verified with build 1.9 M3 rc1
