[Gnuk-users] udev rules for Ubuntu 14.04

[NIIBE Yutaka]

Hello,

Sorry, I was busy for my paper works to tax agency.  Now is the season
in Japan for filing such forms.

No, I don't put binaries now.

When gitorious.org was in service, I put the binaries there.  But I
didn't got any positive feedback for that.  Perhaps, I just couldn't
catch the voice from silent users.

Now, I don't put the binaries on the net.  That's because:

   (1) GNU Toolchain (binaries) are now easier to install.

       In 2010, we need a specific patch set.  Now, we have
       gcc-arm-embedded project.  On Debian, we have
       gcc-arm-none-eabi package to just install by apt-get.

   (2) I'm not sure how users can be sure for the authenticity of
       the code.  I assumed a user wants the souce code when she
       install the binary, but I might be wrong.

It would be possible for me to prepare a GPG key for binary release
and privide GPG signature for binaries, so that users can check.

Thank you for the documentation.  FWIW, my documentation is here:

Let me comment yours.

This is good recommendation.

Yes, something like this is needed.  This is to recognize the reGNUal
device which is used in the firmware upgrade process.

I don't think if you just want to use NeuG, installing gnupg,
gnupg-agent, pcscd is not the requirement here.

I think that the only mandatory tool is python-usb.

Installing rng-tools is to run the NeuG device.

Leaving this coniguration file is OK.

I'm not sure if Ubuntu 14.04 adopted systemd or not.  If it's systemd
based, it would be good to have the configuration for systemd, because
it allows multiple instances of NeuG devices to be connected.
