Public bug reported:
The uutils version does not seem to report the filesystem type
correctly:
root@u1:~# stat -f --printf='%T\n' /sys//fs/cgroup/
UNKNOWN (0x63677270)
root@u1:~# stat -f /sys/fs/cgroup/
File: "/sys/fs/cgroup/"
ID: 586d3e54c17eb980 Namelen: 255 Type: UNKNOWN (0x63677270)
Block size: 4096 Fundamental block size: 4096

root@u1:~# stat --version
stat (uutils coreutils) 0.1.0
Whereas the GNU one produces correct output:
root@u1:~# gnustat -f --printf='%T\n' /sys//fs/cgroup/
cgroup2fs
root@u1:~# gnustat -f /sys/fs/cgroup/
