Is there support for using buildx command with a rootless docker daemon? I tried the default buildkit image and the rootless one but both raises this error while booting up buildkit:

error: Error response from daemon: OCI runtime create failed: container_linux.go:370: starting container process caused: process_linux.go:459: container init caused: write sysctl key net.ipv4.ping_group_range: write /proc/sys/net/ipv4/ping_group_range: invalid argument: unknown

As a workaround, I found out that manually running buildkit with rootless config worked

docker run --name buildx_buildkit_builder0 -d --security-opt seccomp=unconfined --security-opt apparmor=unconfined --device /dev/fuse moby/buildkit:rootless --oci-worker-no-process-sandbox

You just gotta make sure that the name of the container matches the name of the buildx builder. In this case, my builder was named "builder" so the buildkit container had to be named "buildx_buildkit_builder0"
