Public bug reported:
For example:
At some point walinuxagent started doing "auto updating", which we
disabled in the distribution (see bug 1650522). We disabled by patching
the conffile to explicitly set AutoUpdate=n.
However, if a user had modified that conffile and then automatically
updates (for example Xenial has unattended-upgrades enabled by default),
then either the user won't see any conffile prompt, or could see one,
won't realise the significance of it and choose the default, which is to
keep the old configuration.
Then the code will default to AutoUpdate=y because it sees no explicit
AutoUpdate=n in the conffile. User behaviour will change from not auto-
updating to auto-updating as a result of the SRU.
There are two problems here:
1) SRUs keep changing conffiles. The moment a user changes a conffile,
that will stop happening for automatic updates. Then there's no point in
changing conffiles for that set of users. If that's OK, then was there
any need to change the conffile in the first place?
2) The patch for disabling AutoUpdate should change the default as
interpreted by the code when not specified in the conffile, rather than
trying to patch the conffile.
Let's track problem 1 in this bug. I filed bug 1657524 to track problem
2.
