systemd version 25 appears to set name equal to type for all virtual
filesystems:
typedef struct MountPoint {
const char *what;
const char *where;
const char *type;
const char *options;
unsigned long flags;
bool fatal;
} MountPoint;
static const MountPoint mount_table[] = {
{ "proc", "/proc", "proc", NULL,
MS_NOSUID|MS_NOEXEC|MS_NODEV, true },
{ "sysfs", "/sys", "sysfs", NULL,
MS_NOSUID|MS_NOEXEC|MS_NODEV, true },
{ "devtmpfs", "/dev", "devtmpfs", "mode=755",
MS_NOSUID, true },
{ "tmpfs", "/dev/shm", "tmpfs", "mode=1777",
MS_NOSUID|MS_NODEV, true },
{ "devpts", "/dev/pts", "devpts", "mode=620,gid="
STRINGIFY(TTY_GID), MS_NOSUID|MS_NOEXEC, false },
{ "tmpfs", "/run", "tmpfs", "mode=755",
MS_NOSUID|MS_NOEXEC|MS_NODEV, true },
{ "tmpfs", "/sys/fs/cgroup", "tmpfs", "mode=755",
MS_NOSUID|MS_NOEXEC|MS_NODEV, false },
{ "cgroup", "/sys/fs/cgroup/systemd", "cgroup",
"none,name=systemd", MS_NOSUID|MS_NOEXEC|MS_NODEV, false },
};
