Adding a custom script during startup

[stuckless]

While the docker container tries to do many things, it's likely that there are configurations that will require extra tweaking.

During startup if the following script exists in the SAGE_HOME (ie, root of the sagetv server) then it will get executed.

sagetv-user-script.sh

(Full path inside the container is)

/opt/sagetv/server/sagetv-user-script.sh

This script must be a valid linux script. ie...
1. Must have a script header like

#!/bin/bash

2. Must be executable

# chmod 775 sagetv-user-script.sh

3. Must be an in unix format (ie, if you are creating/editing this file from Windows, make sure the editor that you are using supports saving a file unix line endings). (If you are editing this file using vi, vim, or nano, etc, it will already have the correct line endings)

So, using the "sagetv-user-script.sh", you can do whatever you want BEFORE sagetv is started.

Does SageTV wait for this script to complete before executing or does it execute SageTV concurrently with this script? Let's say I wanted to use a SageTV startup script to restart my HD-PVRs. If I ran the script to do a power cycle and then waited 10 seconds (or longer) would I be good?

It should wait. The intention was really to add a hook to do something important BEFORE sagetv was started.

Ok then I think this could be a good way to restart my HD-PVRs rather than using a cron job that runs during the weekly backup process described here.

On a related note - what is the easiest way to have SageTV trigger a SageTV system message when the service restarts? I use your notification plugin so this way I will see when this happens.

Did you write a script to reboot your HD-PVRs. If so, could you share? I'd like to do the same.

I can share it but unless you have the same hardware, which in my case is a Digital Loggers web controlled power switch, then it won't be of any use to you. How to you plan to switch the power on and off?

My fault, I was thinking you were telling them to reboot directly over the HD-PVR USB connection. I might be able to do it with my UPS. I'll look into it. Thanks.

What user does this script run as?

It runs as sagetv. It also takes care of the ownerships and file format (ie, settting it properly) before running it.
