该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。
