True. But also, /etc/sudoers should not be readable by
anyone other than root:
On f37:
$ rpm -qlv sudo | grep /etc/sudoers$
-r--r----- 1 root root 4375 Mar 1 2023 /etc/sudoers
If you have edited the file manually, your editor may have
screwed up the mode. You should use visudo to edit the
file, generally.
