The following allows a user definition to specify that a created user entry should not have a password value set. Original implementation allowed a user definition to provide a password value of "=" (no quotes) to generate a crypt-encoded empty string value. In some cases, it may be desired to have no value specified for a user's password. By using a value "-" for a password, no value will be set in the shadow value. An example when this can be used is when logging into a terminal. Logging into a session with an encoded empty password will prompt a user to enter a password since it does not know the password is empty. If the password field blank, a login session will not prompt for a password. Signed-off-by: James Knight <james.knight@rockwellcollins.com> Acked-by: "Yann E.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC.
