Comment 2 for bug 1916390

The requirement for fuse comes from launchpad-buildd; because livefs builds happen inside a lxd container, fuse is required in order to be able to do mounts during the build. To support fuse3 we will need to arrange some sort of a migration.

Why is fuse3 provided as a separate source, instead of being version 3 of the fuse package? If we are going to move to supporting fuse version 3 (i.e. migrating to having it in main), the preferred method is to make the fuse package version 3 so that upgrades work correctly.
