O pacote base-passwd
garante a presença de certos usuários e determinados grupos em um sistema. A documentação está em /usr/share/doc/base-passwd/users-and-groups.txt.gz
(ou /usr/share/doc/base-passwd/users-and-groups.html
) (fonte disponível online em http://anonscm.debian.org/cgit/users/cjwatson/base-passwd.git/tree/doc/users -and-groups.sgml # n138 "> Alioth ):
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."
Portanto, faz parte da especificação LSB e, como o Debian costumava visar a conformidade com o LSB, o Ubuntu tem um bin
usuário e grupo.
