带有内置应用程序的 FreeBSD 内核映像

  • 772

我有创建 FreeBSD 内核映像的经验，但有没有办法在映像中包含应用程序，例如 SQlite 数据库？我想要实现的是将镜像构建中的应用程序打包为一个。

    有没有办法在图像中包含应用程序，例如 SQlite 数据库？

    是的。这是。挂载您的自定义映像或公开可用的映像之一，并使用pkg安装软件包。使用选项-r。报价：

    -r  <root directory>, --rootdir <root directory>
         pkg will install all packages within the specified <root
         directory>.

    笔记：

    例子

    • 从镜像创建内存盘/dev/md0
    shell> mdconfig -a -t vnode -u 0 -f FreeBSD-13.1-RELEASE-amd64.raw
    • 显示分区
    shell> gpart show /dev/md0
=>       3  10552467  md0  GPT  (5.0G)
         3       123    1  freebsd-boot  (62K)
       126     66584    2  efi  (33M)
     66710   2097152    3  freebsd-swap  (1.0G)
   2163862   8388608    4  freebsd-ufs  (4.0G)
    • 将分区挂载到/mnt并列出目录
    shell> mount -t ufs /dev/md0p4 /mnt
shell> ll /mnt
