As sometime, I must have screwed up and chown “/” to user:user, from root:root.
drwxr-xr-x. 18 wbs wbs 8192 May 1 09:48 .
drwxr-xr-x. 18 wbs wbs 8192 May 1 09:48 …
Any issue if I chown root:root / ??
I suppose not, as long as you did not “chown -R /”
On my system, the root folder has permissions dr-xr-xr-x.
The root folder “originates” from package “filesystem”, if you type
“rpm -V filesystem”, the permissions of 17297 folders will be checked.
In your case:
[root@pcbeneden hj]# rpm -V filesystem
.M...UG.. /
[root@pcbeneden hj]# chmod u-w /
[root@pcbeneden hj]# chown root:root /
[root@pcbeneden hj]# rpm -V filesystem
[root@pcbeneden hj]#

Yes, major problems.
Was the change done only in the / directory or was it done recursively so it affects the entire system?
If only contained to the / directory ( ls -l / shows the changes but ls -l /usr does not ) then it is relatively simple to fix.
If done recursively then it is almost mandatory to do a new clean reinstall in order to recover.
The post above shows a quick way to check
The rpm command has an option to fix file system permissions. For example
rpm --restore filesystem
to fix files and directories owned by the package filesystem.
To fix everything you can run
rpm --restore -a
That will run for quite some time.

No only "".
everything else is owned by root:root
Thanks Jeff.
ran:
[root@mcq maps]# rpm -V filesystem
.M...UG.. /
[root@mcq maps]# ls /
then followed your steps.
then ran:
[root@mcq maps]# rpm -V filesystem
[root@mcq maps]#
[root@mcq /]# ls -al
total 52
