   this, for example, prevents running chisel-releases spreads with docker backend

   I'm probably not understanding that statement properly, but you can run the native build host chisel in a container to build for another arch via --arch?

   Generally you would not want to defer to QEMU to build images for other arches the process with chisel will be much faster when it avoids that and runs with a native arch:

   # Custom chisel image/stage until an official image is published:
   # Use the build host native arch only:
   FROM --platform=${BUILDPLATFORM} alpine AS get-chisel
   ARG CHISEL_VERSION=1.3.0
   ARG BUILDARCH
   ARG CHISEL_RELEASE="https://github.com/canonical/chisel/releases/download/v${CHISEL_VERSION}/chisel_v${CHISEL_VERSION}_linux_${BUILDARCH}.tar.gz"
   # NOTE: `--no-same-owner` used as `chisel` release has ownership of `1001:128`
   RUN wget -qO - "${CHISEL_RELEASE}" | tar -xz --no-same-owner -C /usr/local/bin chisel
   
   
   # The forced platform above will get used here too:
   FROM get-chisel AS root-fs
   # Still required to create the root target upfront:
   # https://github.com/canonical/chisel/issues/206
   WORKDIR /root-fs
   # This approach is brittle if using more niche archs, but workaround is rather verbose/inconvenient:
   # https://github.com/canonical/chisel/issues/223
   ARG TARGETARCH
   # Symlink `sh -> bash` is added to support the default SHELL (only dash slice adds the symlink)
   RUN --mount=type=cache,target=/root/.cache/chisel,id="chisel-cache-${TARGETARCH}",sharing=locked \
     chisel cut --release ubuntu-24.04 --arch "${TARGETARCH}" --root /root-fs base-files_base bash_bins && \
     ln -s bash /root-fs/usr/bin/sh
   
   
   # Any `RUN` here for non-native target will be via QEMU,
   # Image will then be exported for the target platform
   FROM scratch
   COPY --link --from=root-fs /root-fs /

   While you could avoid the --platform constraint and use QEMU to avoid the --arch caveat, as noted in my closed issue if you're dependent upon a niche/legacy arch, that won't work (unless custom building chisel?), and of course it'd be much slower.

   i confirm that i don't see this anymore after #274 ( in binaries from https://github.com/canonical/chisel/releases/tag/v1.4.1 )
