Implementation of operational system via SBD

[JimCircadian]

• Evaluate installation medium
  • SD booting of 2.6 - the original flavour of TS7400 installations
  • SD booting of 4.9
  • MMC booting of 4.9 using the image replication processing #18 - this is moved out until Capture modifications for Linux 4.9 / squeeze installation #17 is done and we're ready for imaging
• Run over ansible provisioning mechanism
• Get basic installation working for pyremotenode
• Configure an example

[JimCircadian]

Basic update to blank OS, looking at 4.9 installation medium and associated caveats and getting the provisioning mechanism up and running. 4.9 is likely a sensible move, there is an option on 5.10 but this doesn't appear as well founded as 4.9 and is more recent, though will offer longer term support so should be attempted if 4.9 works.

[JimCircadian]

Starting with 4.9

1. Setting up network and SSH
2. APT sources as archive.debian.org, apt-get update

[JimCircadian]

The image replicator processing should be used once the build is finished to flash the eMMC.

pyremotenode and apscheduler (dependency) installed successfully using the ansible provisioning.

Had to get the IMEI set up correctly, SBD now working. RUDICS also verified whilst I was at it, just to make sure the internet endpoint was still available to the ISU:

+CR: REL ASYNC

OK

Debian wheezy (original) build as opposed to squeeze is required. The pyremotenode installation on wheezy fails due to the age of the SSL certificates on the system.

However, squeeze requires substantial changes to the hardware interfacing for pyremotenode, #17, so the minimal viable installation is working on wheezy as well.

Command running, producing configuration via the ansible setup at BAS for pyremotenode basic functionality:

run_pyremotenode --help
usage: run_pyremotenode [-h] [--log-dir LOG_DIR] [--start-when-fail]
                        [--pidfile PIDFILE] [--no-pidfile] [--no-daemon]
                        [--verbose]
                        config

positional arguments:
  config                Configuration to use for running remote node

optional arguments:
  -h, --help            show this help message and exit
  --log-dir LOG_DIR, -l LOG_DIR
                        Log directory
  --start-when-fail, -s
                        Start even if initial monitor checks fail
  --pidfile PIDFILE, -p PIDFILE
                        PID file to manage for service operations
  --no-pidfile, -np     Don't check or create PID file
  --no-daemon, -n       Do not daemon
  --verbose, -v         Debugging information

Two versions created: ts7400-lx26-lpm and ts7400-lx49-lpm as SD based images for deployment in Halley.
