Let me know what you think.

Longsleep,

  Noob nere. I keep seeing "image." Ubuntu image, download image, etc, etc image.
I thought images were pictures.
What exactly does it mean to say; "Ubuntu image"?
Thank you.

He means a disk volume image.  A disk volume image generally takes the form of a file which is input to the Unix/Linux `dd` utility in creating the actual disk volume.

Ah, so the "disk volume image" creates the place on your SD card for the distro to run?

Roughly, yes.  The disk volume image is a file which is isomorphic to an entire disk of any type: HDD, SSD, USB, MicroSD, etc.  This file is often compressed in some form so to conserve storage and minimize download time.

Hi,

Let me give you an example to help clarify. Basically an image is a reflection of everything on a storage device. For example, I could take an image of my windows hard drive and the result would be a single file that contains everything in my hard drive. (Windows operating system, personal files, images, MP3's, etc/...) I could send you that image and then you could copy it to a hard drive and when you boot it, your computer would look just like mine. In practice, it is very easy to both create images and install images.

In the world of Windows, the easiest tool is called Win32diskimager and it allows you to both take an image and write an image.

In the world of Pine (and pretty much all similar systems) someone creates an image of a known good state and version of Linux. The users then decompress and copy that image to an SD Card and the result is fully bootable Linux OS. In our case, most of the images are maintained by third parties like Longsleep and Lenny.

OK, Got it. It seems though that this terminology "could" create some confusion if, say one person is thinking image, as in; jpeg, bitmap, etc. and another person is thinking image, as in; disk image.
 I guess you would consider the context of the conversation. :-D 
Thanks for clarifying this for me. I appreciate it.


RE: Ubuntu Xenial Image (BSP Kernel) - MagicCamera - 07-08-2016

I am wishing for just a pure basic version of Ubuntu 16.04 server. Command Line Interface only, no desktop no bells and whistles, just a pure server version of Xenial. I have the Ubuntu Mate and I hate it... in fact I can't stand it, it's boring. Anyway, attempting to flash your build but wondering what core root_fs you used or if you can show us how to create an img file of 16.04 server that would be great.

Is someone able to test their PINE64 in order to see if the behaviour is different please?

ISP limits upload speeds. You get about 20% of upload speed at best.

Desktop GUI's are overrated... give me a pure CLI any day. If I can get the server version loaded, I'll install Node.js and use that to serve up various web apps.

Flashed and up and running CLI only. Just what I wanted. Thanks Longsleep.

All my builds can be reproduced and the building gear is available on GitHub. See https://github.com/longsleep/build-pine64-image/blob/master/simpleimage/make_rootfs.sh#L61 for the details what rootfs is used for Xenial.


RE: Ubuntu Xenial Image (BSP Kernel) - yodermk - 07-09-2016

just jumping in here; can I ask why we're on kernel 3.10? Is it not possible to get current kernels to run on the Pine64?

Thanks!

It's what is provided by the SoC vendor. There is a community driven mainlining process - see http://linux-sunxi.org/Linux_mainlining_effort for details


RE: Ubuntu Xenial Image (BSP Kernel) - bjwschaap - 07-14-2016

Question, if I build a new kernel as per these instructions: https://github.com/longsleep/build-pine64-image/blob/master/kernel/README.md

Can I drop in that kernel into this image? Would replacing `Image` be enough, or are there other/more steps involved?


RE: Ubuntu Xenial Image (BSP Kernel) - longsleep - 07-16-2016

It has been a while and i just released a new Ubuntu build which includes the latest Kernel. No other changes except that also all the other Ubuntu components have been updated to their current repository version.

Download 20160716-1 from https://www.stdin.xyz/downloads/people/longsleep/pine64-images/ubuntu/

If you do not need Kernel modules then replacing the Image file is good enough, else also install the modules with the corresponding script.
