[Qemu-trivial] [PULL 17/18] docs/devel/testing: Add -a option to usermod command on docker setup |

From: Murilo Opsfelder Araujo <address@hidden>
The option -G of usermod command will remove user from other groups
not listed, i.e.: $USER will belong only to group 'docker' after
following the documentation as is.
>From usermod(8) manual page:
If the user is currently a member of a group which is not listed,
the user will be removed from the group. This behaviour can be
changed via the -a option, which appends the user to the current
supplementary group list.
This patch improves the situation by adding the -a option to the
usermod command, which will just append user to the supplementary
group list.
