转义双引号会导致 3 个而不是 4 个参数

Question

strace 表明，与 shell 形式相比，我使用的转义可能会导致问题（shell 形式与 exec 形式请参阅https://docs.docker.com/engine/reference/builder/）

带有 [/* 3 vars */] 的 exec 形式 - 中断/制造麻烦

ENTRYPOINT ["strace", "hugo", "server", "--watch=true", "--bind=0.0.0.0", "--source=\"/src\"", "--destination=\"/output\""]
execve("hugo", ["hugo", "server", "--watch=true", "--bind=0.0.0.0", "--source=\"/src\"", "--destination=\"/output\""], [/* 3 vars */]) = 0

带有 [/* 4 vars */] 的 shell 形式 - 工作正常

ENTRYPOINT strace hugo server --watch=true --bind=0.0.0.0 --source=""/src"" --destination=""/output""
execve("hugo", ["hugo", "server", "--watch=true", "--bind=0.0.0.0", "--source=/src", "--destination=/output"], [/* 4 vars */]) = 0"

Dockerfile：（使用 ubuntu，因为我无法使用 alpine:latest 运行 strace。）

# escape=\
# first line can be removed and doesn't change the behavior of the described issue
FROM ubuntu:latest
RUN apt-get update && apt-get install hugo strace
RUN hugo new site src
WORKDIR /src
ENTRYPOINT ["strace", "hugo", "server", "--watch=true", "--bind=0.0.0.0", "--source=\"/src\"", "--destination=\"/output\""]
EXPOSE 1313

运行并保存输出的命令：

 sudo docker run --security-opt seccomp:unconfined docker-hugo &> docker-hugo.strace

（有关 --security-opt 的信息，请参阅https://github.com/moby/moby/issues/20064#issuecomment-291095117 ）

所以我的问题是：我是否没有正确转义 JSON 数组？
