[Ros-release] sudo not found?

[William Woodall]

Or you can change the permissions of the executable (setuid or setcap) in a
post install hook.

So you would write a script which does this, from source I would run this
script manually after building and from debian this script would be run as
a post install hook.

I haven't setup a post install hook before, but you should be able to do
this in the debian folder of the `debian/groovy/<package_name>` branch in
your release repository (don't for get to run bloom again after the change).

Running `git-buildpackage -uc -us` while on the appropriate debian tag
(something like `debian/ros-groovy-youbot-driver_0.1.2-0_precise`) will
build debs you can test from your release repository. The debs will be
created one folder up.

Hope that helps,
