scripts/build/.variables 文件去掉-w
scripts/build/binary 增加 -gcflags="all=-trimpath=$PWD -N -l"
构建 make -f docker.Makefile binary

```
wget https://github.com/multiarch/qemu-user-static/releases/download/v3.0.0/qemu-x86_64-static.tar.gz

fork 后本地仓库添加，这里例如 skopeo

1. 先添加上游

git remote add upstream https://github.com/containers/skopeo.git

2. 拉取上游

zhangguanzhang

dnf install -y gcc make wget vim git libseccomp-devel systemd-libs systemd-devel jq patch tar

go get github.com/go-delve/delve/cmd/dlv

wget -O /usr/share/containers/seccomp.json https://raw.githubusercontent.com/containers/common/main/pkg/seccomp/seccomp.json

make BUILDTAGS="containers_image_openpgp systemd exclude_graphdriver_btrfs btrfs_noversion exclude_graphdriver_devicemapper selinux seccomp " podman

podman system  service --time 0 tcp:127.0.0.1:8081
