Remove the leftover SONIC_USE_DOCKER_BUILDKIT references that no longer
do anything:
- slave.mk: File: dir, Node: Top This is the top of the INFO tree
This (the Directory node) gives a menu of major topics.

- Makefile.work: passthrough to slave container
The functional code (export DOCKER_BUILDKIT=1/0) was removed in sonic-net#23164
when dockerfiles were updated to use staged builds instead of --squash.
Docker BuildKit has been the default since Docker 23.0 (Apr 2023), and
all active build environments use Docker 24+. These two lines were just
dead code left over from the reland.
History:
- Jun 2019 sonic-net#3049: Created by @stepanblyschak (working, opt-in)
- Apr 2023 sonic-net#14405: Added explicit DOCKER_BUILDKIT=0 for Docker 23+
- Jul 2025 sonic-net#23164: Functional code removed (staged builds), but

There was a problem hiding this comment.
Looks good. Removing the dead passthrough and config print is safe now that BuildKit defaults are standard and the functional toggle is gone.

- Makefile.work: passthrough to slave container
The functional code (export DOCKER_BUILDKIT=1/0) was removed in sonic-net#23164
when dockerfiles were updated to use staged builds instead of --squash.
Docker BuildKit has been the default since Docker 23.0 (Apr 2023), and
all active build environments use Docker 24+. These two lines were just
dead code left over from the reland.
History:
- Jun 2019 sonic-net#3049: Created by @stepanblyschak (working, opt-in)
- Apr 2023 sonic-net#14405: Added explicit DOCKER_BUILDKIT=0 for Docker 23+
- Jul 2025 sonic-net#23164: Functional code removed (staged builds), but

What I did
Removed two leftover
SONIC_USE_DOCKER_BUILDKITreferences that no longer do anything:slave.mk:$(info)print in build config summaryMakefile.work: passthrough to slave containerWhy I did it
The functional code (
export DOCKER_BUILDKIT=1/0) was removed in #23164 when dockerfiles were updated to use staged builds. These two lines were left behind — the variable is printed and passed around but never read.Docker BuildKit has been the default since Docker 23.0 (Apr 2023), and all active build environments (bookworm/trixie slave, host) use Docker 24+.
