Re: IMAGE_INSTALL_append workflow

I'm kinda surprised nobody jumped in on this one; either my question
is so silly it isn't worth anyone's time, or I'm the only one who
wants to add packages to an image after a full build. I know my
question has nothing to do with trace-cmd specifically, adding any
package after a full build results in the same problem.

It would certainly seem odd that the yocto workflow assumes you always
know 100% ahead of time which packages you want in your final image. I
know when I was playing around with Hob this wasn't an issue: I would
simply add the new packages and Hob would build them and add them to
the image.

From what I have seen from skimming the documentation, the
documentation talks at length about how to add a new package to the
configuration, but it doesn't say what commands to issue after
modifying the config files. Obviously running "bitbake <image>" alone
doesn't work.

Today I was playing around with an image I had already built and
decided I wanted to add a new package to the mix: trace-cmd. I added "
trace-cmd" (with the required leading space) to IMAGE_INSTALL_append
and re-ran my "bitbake <image>" command.

It failed:

Unable to resolve package trace-cmd

If I perform:

$ bitbake trace-cmd

and then

$ bitbake <image>

it works fine. What am I missing?

As it turns out, if I knew before my first build that I wanted
trace-cmd, I could have just added it as described above and
everything would have worked as well.
