rootfsdebugfiles.bbclass: quick-and-dirty installation of additional files
The main motivation for this class was the observation that
a) a core-image can hang under qemu when the kernel does not
have enough entropy to generate the ssh host key
b) ssh complains about changing ssh host key files when
rebooting the same machine with different images
For debugging it is okay to reuse an ssh host key generated on the device
before. There may be also similar use cases, so the class is generic enough to
also copy more than one file or directory, with dropbear_rsa_host_key given as
example.
The documentation and naming of the class makes it clear that it
should not be used for production images.
