Requested experimental feature mergeop is not supported by build server

[maxpain]

Hi. I'm trying to build the kernel with these instructions.

git clone https://github.com/talos-systems/pkgs.git
cd pkgs
make kernel PLATFORM=linux/amd64 USERNAME=maxpain PUSH=true

But getting this error:

This is strange, because I could build the kernel a few days ago.

@smira Could you look into this? Maybe it is somehow related to this PR: siderolabs/bldr#86

[frezbo]

it's the version of buildkit you're using is old, please remove the existing builder and re-create. the buildkit uses this image moby/buildkit:buildx-stable-1

Thank you!
