This patch fixes the algorithm that dertermines the mount point for snaps. The old code used to work because it was looking at /etc/os-release and looking for specific ID or ID_LIKE values. With the introduction of base snaps that can have arbitrary os-release files we cannot rely on this information alone. When a process is inside a snap mount namespace that has a base snap mounted as the root filesystem then the os-release level information is not useful and must not be used anymore. Inside that environment the snaps are always mounted at /snap. On the outside of a mount namespace the current algorithm is correct, it will identify the distribution and apply any differences mandated by the distribution policy.
