[yocto] Signed RPMs

[Chris Trobridge]

Hi,
I have been testing out the facility for generating signed RPMs.
It's currently failing to find 'build/tmp/sysroots/x86_64-linux/etc/RPM-GPG-PUBKEY', log listed at end.
I couldn't find a lot of documentation but from what I could find, I added the following to local.conf:
INHERIT += " sign_rpm"RPM_GPG_NAME = "chris"RPM_GPG_PUBKEY = "/home/chris/mykey.pub"RPM_GPG_PASSPHRASE_FILE = "/home/chris/mypassphrase"
It needed 'python-pexpect' installing (fedora 22) to run at all but after that it worked to an extent as I had to correct the stored passphrase to correct other errors.
At this stage of the build there is very little in 'build/tmp/sysroots/x86_64-linux/etc/' (just quilt related) but I also find it curious that it is looking for the variable name rather than it value.
Now I was following the the Aug patch notes "'RPM_GPG_PUBKEY = "<path_to_pubkey>" in bitbake config pointing to the public key (in "armor" format).".
Since then there was a patch "Automatically export public keys used for package(feed) signing" that obsoletes RPM_GPG_PUBKEY (and overwrites it) but I'm still not clear how/where to put the public key so it will end up in the staging directory.  Also, 'package_manager.py' copies the file named by RPM_GPG_PUBKEY to the location os.path.join(self.deploy_dir, 'RPM-GPG-KEY-%s' % distro_version).  I presume this copies from the staging directory to the deployment directory.
So what I would like to know is where to put the RPM GPG public key so that it gets copied to the staging directory?
For the time being, I have copied it in by hand.
Thanks,Chris
