Comment 58 for bug 1828495

Another bunch of related changes might be important.
Not sure how much of that will go into SRUs - I hope not all of it.
Already in Eoan we should try to use a reduced set or we could go directly to 5.5 which has other known issues.

I hope I might get away with only those I marked with XX, but still this keeps growing to an uncompfortable amount
