The recommended way to start off is in permissive mode. Kernel ...253.2.1
does not start in enforcing mode automatically by default.

One thing you can do is duplicate the lines in grub for a particular kernel
and add ENFORCING to the title and enforcing=1 to the end of the kernel
line. That way you can start off in either mode.

The way to see which mode is to "cat /selinux/enforce"  0 is permissive.  To
change to enforcing while running "echo 1 > /selinux/enforce".
