[Buildroot] [PATCH 1/4] scripts/mkusers: allow the creation of groups alone

[Yann E. MORIN <yann.morin.1998@free.fr>]

Gustavo, All,

On 2014-10-21 11:26 -0300, Gustavo Zacarias spake thusly:
> Let mkusers create groups alone, useful for supplementary permissions in
> udev/systemd for example where users can be added to later at runtime.
> Use a magic string "-" to signal that user creation should be skipped.

Gah, FIFO de-queuing. You beat me to it! :-)
