Debos工程：

go-debos

Debos是一个使用GO开发的相对简单的debian文件系统构建工具，提供了以下的命令：

Some of the actions provided by debos to customize and produce images are:

• apt: install packages and their dependencies with 'apt'
• debootstrap: construct the target rootfs with debootstrap
• download: download a single file from the internet
• filesystem-deploy: deploy a root filesystem to an image previously created
• image-partition: create an image file, make partitions and format them
• ostree-commit: create an OSTree commit from rootfs
• ostree-deploy: deploy an OSTree branch to the image
• overlay: do a recursive copy of directories or files to the target filesystem
• pack: create a tarball with the target filesystem
• raw: directly write a file to the output image at a given offset
• recipe: includes the recipe actions at the given path
• run: allows to run a command or script in the filesystem or in the host
• unpack: unpack files from archive in the filesystem

步骤：

1.安装必要软件： 

sudo apt install golang git libglib2.0-dev libostree-dev qemu-system-x86 \
     build-essential qemu-user-static debootstrap systemd-container \
     binfmt-support policykit-1 parted dosfstools xz-utils bmap-tools

2.设置环境：

sudo systemctl start systemd-resolved
export GOPATH=`pwd`/gocode
go get -u github.com/go-debos/debos/cmd/debos

 3.根据配置文件构建：

sudo debos debian.yaml     #假设你的配置文件为 debian.yaml

 可供参考的YAML文件 

 若构建过程出现错误提示如下：

chroot: failed to run command '/debootstrap/debootstrap': Exec format error

则：

sudo apt-get remove qemu-user-static     #卸载
sudo apt-get install qemu-user-static    #重装

sudo update-binfmts --enable #构建之前运行

说明：

qemu-user-static服务为程序运行构建虚拟环境，比如在你电脑上模拟ARM运行环境；

update-binfmts服务为文件指定特定程序运行，类似Windws根据文件后缀指定运行程序；
