Prior to this change, the udev rules were fixed to allow read-write
access only to the `plugdev` group. However, while this is the default
group for USB input devices on Debian and its derivatives, this is not
true for some systems such as openSUSE, which use `input` as the group.
This change adds a `--with-input-group` argument to `configure`, which
defaults to `plugdev`. This change also updates the install
documentation to reflect the new options.
When testing make install in a container, or if being run with fakeroot,
it is possible that the udevadm commands may fail, which will abort the
install. Therefore, allow the udev install hook to always pass.
Prior to this change, a user had to manually install their own udev
rules on Linux if they wanted to access the joystick without having to
run as root. The most common usecase was on systems based on Debian,
where the user would be a member of the plugdev group, and they would
create their own rule to allow members of the group to write to the
joystick.
This change adds a validated udev rule to the distribution, so if the
user compiles from source and does a make install, the rule to allow
plugdev group members to access the joystick is installed.
