[Sugar-devel] [SoaS] SOAS

[James Cameron]

G'day David,

I've no guidelines.  There are some industry best practices, but they
boil down to;

- conditions of sale, e.g. the seller warrants compatibility with
  Linux, or fails to,

- compatibility testing, e.g. running an uncustomised Linux such as
  Fedora, and verifying it works with enough stability,

- component testing, e.g. a memory tester,

- scenario testing, e.g. sleep and wake, lid close, lid open, wireless
  access, USB device access, sound playback, sound capture, video
  playback, video capture,

For hardware being repurposed, it helps to know where you got it from,
and what it has experienced.  A memory test may help to find thermal
problems, like dust in fans, or battery longevity.

Otherwise, it's a never ending problem.  ;-)

With some of the computer types we were using in the workshop it works well, but with others it might freeze after a few minutes, or not quite complete the boot sequence. We tested the 32-bit and 64-bit and several types of USB drive, reinstalled the USB drives and confirmed that there is a lot of hardware dependency. The only computer I have that it works on every time and never freezes is a small ASUS EEE PC network 6 years old.

But we found sometimes the boot sequence works fine and other times (especially when trying to demonstrate to a group) it would not start the Live boot sequence but go into Grub instead. So not very reliable way to do that either.

It also installs a Linux emulator for Windows Virtualbox and I found I could run SOAS beautifully in that way. That is very convenient for my purposes (a quick lead in to Sugar). I also found few problems booting USB sticks and SD cards installed using LinuxLiveUSB, on one machine it seems to hang but others it is fine. So it seems the installer was my issue.

I seem to recall doing that with early versions of SOAS. If not, is there a simple/light way to enable collaboration/presence service on a local server sufficient to allow a few local SOAS machines to collaborate?. I am familiar with XS developments (up to 0.7) but in the schools in Vanuatu we'll be using gateway servers we have developed ourselves based on Debian (Jessie 8).

I would like to be more useful, but actually don't have the luxury of time to research these arcane technical issues in which I am not an expert. I just want to know, is there a version of SOAS that is properly tested and known to work? I have used SOAS many times before (years ago) without any problems. Which version is stable and will boot without errors and not hang on use?
