28 | are not removed, and static configuration applied by networkd | |
29 | is not removed when networkd exits. Dynamic configuration applied by | |
30 | networkd may also optionally be left in place on shutdown. This ensures | |
31 | restarting networkd does not cut the network connection, and, in particular, | |
32 | that it is safe to transition between the initrd and the real root, | |
