I’ve just discovered you can switch selinux into Permissive mode whilst the machine is running

This shows that we are currently enforcing:

# sestatus
SELinux status:                 enabled
SELinuxfs mount:                /selinux
Current mode:                   enforcing
Mode from config file:          enforcing
Policy version:                 21
Policy from config file:        targeted

To switch into permissive mood:

# setenforce Permissive

And another sestatus shows the change

# sestatus
SELinux status:                 enabled
SELinuxfs mount:                /selinux
Current mode:                   permissive
Mode from config file:          enforcing
Policy version:                 21
Policy from config file:        targeted
