Comment 5 for bug 1882993

Note that in particular, lightdm seems have to problems when using v1 policies, see https://github.com/google/fscrypt/issues/203. I had to upgrade one focal laptop to v2 policies to get lightdm to work - although oddly I had no problems on another, and I can't see the difference between them.

I would have thought a backport for at least focal might have been justified, as home directory encryption must be one of the major use cases for fscrypt.
