base-passwd软件包可确保系统中某些用户和某些组的存在。该文档位于/usr/share/doc/base-passwd/users-and-groups.txt.gz(或/usr/share/doc/base-passwd/users-and-groups.html)中(可从Debian Salsa在线获得资源):

bin

    HELP: No files on my system are owned by user or group bin. What good are
    they? Historically they were probably the owners of binaries in /bin? It is
    not mentioned in the FHS, Debian Policy, or the changelogs of base-passwd
    or base-files.

    LSB 1.3 lists bin as legacy, and says: "The 'bin' UID/GID is included for
    compatibility with legacy applications. New applications should no longer
    use the 'bin' UID/GID."

因此,它是LSB规范的一部分,并且由于Debian过去一直致力于LSB遵从性,因此Ubuntu具有bin用户和组。

/usr这是历史悠久的Unix中用户家园的原始路径,因此有一个bin用户负责/usr/bin-比较在这些系统(以及一些更现代的系统-Solaris等)中如何实现root用户,但/没有/root,作为主目录。
