add post-refresh hook to restart subiquity on the serial line For https://bugs.launchpad.net/subiquity/+bug/1848182. This was easy? As a bonus, the hook from the refreshed-to snap is executed so this will work even when the user is running current media. 2019-10-17 00:26:14 +00:00			`#!/bin/sh`
more reliably restart client when server restarts Splitting subiquity into server and client means that in general old versions of the client can still be running when the server is updated (the client running on tty1 will be restarted by snapd/systemd when the snap is updated but clients running via e.g. ssh will not). I implemented a way for the client to detect this and restart itself: the server sets a header in all responses that indicates if it has been updated. So far so good. But the way it knows that it has been updated is to check the presence of a file that is only created when subiquity itself triggers the refresh, so it's not there in the case of manual refresh, and as reported in https://bugs.launchpad.net/bugs/1921820 this can lead to the client crashing because it cannot parse the new server's response. This simply changes to creating the marker file in the snap post-refresh hook, which will be executed for manual snap refreshes as well. While I'm at it, remove the rest of the post-install hook that restarted subiquity clients running on the serial line as the generic machinery will work for these too. 2021-03-30 23:19:55 +00:00			`mkdir -p /run/subiquity`
