I encountered a problem with chown on my fedora34 as the version of
coreutils is 8.32.
The reproduce process could see the steps blow:
[root@fedora ~]# ll test.txt
-rw-r--r--. 1 root root 0 Dec 13 21:13 test.txt
[root@fedora ~]# chmod 4750 test.txt
[root@fedora ~]# ll test.txt
-rwsr-x---. 1 root root 0 Dec 13 21:13 test.txt
[root@fedora ~]# chown root:root test.txt
[root@fedora ~]# ll test.txt
-rwxr-x---. 1 root root 0 Dec 13 21:13 test.txt
[root@fedora ~]# rpm -qa coreutils
coreutils-8.32-19.fc34.x86_64
[root@fedora ~]# cat /etc/fedora-release
Fedora release 34 (Thirty Four)
Looking forward to hearing from you!
Thanks.
