Comment 6 for bug 1901578

I was curious where we do this so I went looking and this is the start of the problem:

https://github.com/snapcore/snapd/blob/7ff96a40a7a7a7779db250b087cec9b183540130/overlord/snapshotstate/backend/helpers.go#L145

In absence of other information, we snapshot the state for all the users this way.
