[PATCH v2] kernel.bbclass: Create symbolic link to add ${KERNEL_IMAGETYPE} to boot package

[PATCH v2] kernel.bbclass: Create symbolic link to add ${KERNEL_IMAGETYPE} to boot package

[Franklin S. Cooper Jr]

* By default for some platforms U-boot assumes the kernel image is located in
  the boot directory of the root filesystem.
* The kernel.bbclass already includes the kernel image in the /boot directory
  but adds a version number to the file name.
* Create a symbolic link that names the kernel image in the exact way that
  U-boot expects.

Version 2 changes:
Change "ln -s" to "ln -sf" based on Bruce's comment.

This should be done with a package post-install script.  It is fairly common for 
multilib kernel versions to be installed on a machine at the same time, with the 
Link pointing to the 'last-installed' version.  Doing it in the do_install rule 
will cause a conflict (at least in the RPM case), preventing certain field 
upgrade activities.

post install script with something like:

ln -sf $D/boot/<kernel_name> <common-name>

Should work.

(The above assumes that the kernel itself is being packaged.. if it's not being 
packages and just copied to the end image -- then doing the link should be fine.)

Looks like the below patch addresses my issue and also handles it in the
same way you recommended.
