The semi regular basis is only slightly moved, or how and when will replacing the already EOL kernel 5.0 with 5.1 in Yocto be handled? IMHO it would be better to acknowledge that this is a case where staying at stable release versions is sometimes not the best option, and upgrade the normal recipe to -rc releases or even a git snapshot from a more recent stable branch when necessary. E.g. right now it seems clear that the next Yocto release will have to use lttng-modules >= 2.11 in any case for kernel 5.2, so upgrading from 2.10.9 to 2.11.0-rc5 would be logical. > Cheers, > > Richard cu Adrian -- "Is there not promise of rain?"
