构建定制化Ubuntu镜像全流程指南
在构建定制化的Ubuntu镜像时，我们需要进行一系列细致的操作，包括环境配置、种子文件处理、元包生成以及安装程序预配置等。下面将为你详细介绍整个过程。
环境配置
在开始构建镜像之前，我们需要对一些环境变量进行设置，以确保构建过程的顺利进行。以下是相关的环境变量配置代码：
# Do not update the local mirror CDIMAGE_NOSYNC=1 LOCAL_SEEDS=file:///home/<username>/devel/ubuntu/seeds/ CDIMAGE_ROOT=`pwd` CDIMAGE_INSTALL=1 CPUARCHES="$(echo "$ARCHES" | xargs -n1 | sed 's/+.*//' | sort -u | xargs)" GNUPG_DIR="$CDIMAGE_ROOT/secret/dot-gnupg" SIGNING_KEYID=1421BE56 # Mirror info MIRROR= MIRRORDIR= # Hosts that need to be notified when the build is done. Third-party users # will want to keep this variable empty. # The “async” mirrors will be notified asynchronously, i.e. we won’t wait for # them to respond. TRIGGER_MIRRORS= TRIGGER_MIRRO
