Hello,<br /><br />i am working with "Morty" release of yocto. Due to organizational reasons we still have to use "Morty" but will be upgraded soon.<br />But, there are some certificates missing in the OpenSSL truststore. Now, I would like to add them to the image during build. Certificates are mainly for Amazon services (Amazon_Root_CAs). I beleive this can be done with ca-certificates_%.bbappend. I would like to know how will the .crt files be converted to .pem format and also how will ca-certficates.crt file will be updated in /etc/ssl/certs/ dir? The recipe is&nbsp;http://cgit.openembedded.org/openembedded-core/tree/meta/recipes-support/ca-certificates/ca-certificates_20160104.bb?h=morty
