Great. Didn't realise that was going to work!
Well, unless something has been changed/fixed recently (and I believe it was Richard's do_rootfs fixes), it didn't use to work as easy as you'd expect and it would break in do_rootfs, when trying to nest image types directly, hence the implementations like these: http://cgit.openembedded.org/openembedded-core/tree/meta/classes/image_types_uboot.bbclass http://arago-project.org/git/?p=meta-arago.git;a=blob;f=meta-arago-distro/classes/image_types_md5.bbclass;hb=HEAD BTW, at least for md5sum (not sure about sha*), isn't the de-facto standard extension .md5 and not .md5sum? Can we change it? -- Denys -- _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.openembedded.org/mailman/listinfo/openembedded-core
