[Buildroot] [PATCH 1/1] system: add ability to pass additional users tables.

Thu Mar 27 16:19:36 UTC 2014


A new entry has been added to the "System Configuration" menu to allow
the user to set the location of additional user tables (besides the ones
defined in packages).

A user table is a text file, formatted using the mkusers syntax, which
describes the users on the target system, with their UID/GID, home
directory, password, etc.

The target root file system will be populated according the content of
these files.
