You already did the first step and verified the build of the relevant components (snapd and snap-confine) works well in OpenSwitch. The next step is to get the different config options for the kernel into your kernel defconfig. We have various sample kernel trees at [1] which you can use as reference. In meta-snappy I extended the default linux-yocto defconfig with the bits listed in [2]. I suspect OpenSwitch may use a different kernel tree so you have to apply the different options for it as well. You don't need any AppArmor related patches if you want just unconfined snaps working for a first step. As next thing you have to add snapd and snap-confine to the content of the OpenSwitch image. Adding snap-confine and snapd in [3] is ok to get it things working. Later you want to add a packagegroup especially for snappy which I am planing to add to meta-snappy which then will automatically pull in all necessary dependencies for you. Once that is done you should be able to build a regular OpenSwitch image, flash it on a device or boot it in an emulator and should have snapd running and being able to install snaps and run their applications. If you need further help or have questions, just ask here or ping me (nick morphis) on IRC in #snappy on FreeNode. regards, Simon [1]: https://github.com/snapcore/sample-kernels [2]: https://github.com/morphis/meta-snappy/blob/master/recipes-kernel/linux/files/snappy.cfg [3]: https://git.openswitch.net/cgit/openswitch/ops-build/tree/yocto/openswitch/meta-distro-openswitch/recipes-core/packagegroups/packagegroup-openswitch.bb?h=feature/yocto_2.1 -- Snapcraft mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/snapcraft
