Some sysctl custom parameters can't be applied in one commit.
For example, if the tunnel interface does not exist yet.
1.3:
```
set interfaces ethernet eth1 address '203.0.113.1/24'
set interfaces tunnel tun0 address '100.64.0.1/30'
set interfaces tunnel tun0 encapsulation gretap
set interfaces tunnel tun0 source-address '203.0.113.1'
set interfaces tunnel tun0 mtu '1500'
set interfaces tunnel tun0 multicast 'enable'
set interfaces tunnel tun0 parameters ip ttl '64'
set interfaces tunnel tun0 remote '203.0.113.2'
set system sysctl custom net.ipv4.conf.tun0.accept_local value '1'
