本文关键字：自建udeb站镜像。local repository debian installer preseed,Preseed install from local repository,start http server in a preseed file,debian中用NC+SHELL实现的一个web服务,浏览器装机,Preseed failed with exit 2,d-i preseed/early_command string stuck hang,linux grep -o 只匹配字串
继把Debianinstaller当online packer用文章1，本文继续讲解生成packerpe。
给前面的脚本增加和镜像格式判断，统一wget和dd progress
增强主要是为了pipecmdstr处整合，稍后会看到(因此也顺便支持了onelist,oneindex这种网盘外链作为ddurl地址，其实质是302跳转体)。这段替换前文的cd /tmp/boot;到echo -e "Downloading kernel : ${LinuxMirror}/....../debian-installer/amd64/initrd.gz"间的内容：

}如果你发现启动不了文件系统出现制作文件系统时出现的那些错误，那就是可能glibc低了。注意到dd status progress我并未在接下的preseed中用到。

}注意上面的脚本中输出至preseed file至EOF止的内容必须顶格写，Ks.cf是installment.sh用来用同样ubuntu支持preseed支持centos的方法。已删，在文件中，我注释了原来使用内置的webfsd服务器作镜像的方案，因为preseed early command string中欠入webfsd启动命令（放anna install前），会导致PE启动时early command运行时，umount时前台却在加载webfsd卡住，需要ctrlc才能继续，但实际上webfsd已成功运行。
所以我将注释webfsd的逻辑放在preseed中某位置，这个位置是它应该启动时的时机。实际上early command string中都不比它合适。未来想办法让它以正确方式起作用。

这个脚本还有其它很多需要增强的地方，比如dd progress显示。还比如改成了生成双分区。保留packerpe到第一分区。整盘其实可以preseed/partman成二个分区，一个分区200M放生成的packerpe自身（未来，还可以在这个packerpe集成dbcolinux或集成linuxbpot,coreboot，clover等），
还比如，扩展镜像到整个磁盘空间，实际上windows通过ntfs fuse是实现了的。对于linux磁盘，要处理镜像分区表适配到目标整个磁盘。这不光适用于dd方案。也适用于将磁盘打包成dd镜像（脚本中改变pipecmdstr，镜像扩容缩容）。然后nc 监听，供其它机器下载其镜像或直接dd。这是这个脚本的反向功能。
还比如，利用webfsd的cgi改dd地址。也可用grub的auto url变换dd地址。Ddurl参数保留到下一次。且读取位置不再在preseed中。
但是我不想做了，以后继续吧。这些天做windows server 2019 core的dd镜像也较累了，用了跟做osx云镜像差不多的方法：在linuxkvm中套虚拟机。
