I just try it again and notice that i forgot to add `-r` flag to rm
without this flag:
```
rm: cannot remove ‘/etc/ipsec.d/cacerts’: Directory not empty
rm: cannot remove ‘/etc/ipsec.d/certs’: Directory not empty
rm: cannot remove ‘/etc/ipsec.d/examples’: Directory not empty
rm: cannot remove ‘/etc/ipsec.d/policies’: Directory not empty
rm: cannot remove ‘/etc/ipsec.d/private’: Directory not empty
```
Also fix markup - set bold instead italic for more attention
