** Description changed: As reported by Jann Horn on bug 1850994, unprivileged overlayfs mounting fails in disco/eoan due to SB_I_NOSUID and SB_I_USERNS_VISIBLE. overlayfs sets SB_I_NOSUID for unprivileged mounts, which causes mount_too_revealing() to bail out as it sees SB_I_USERNS_VISIBLE as being set. - - Xenial has a differing conflict of s_iflags, which does not prevent - unprivileged overlayfs mounts, but it should still be fixed.
