** Description changed: + [Impact] + Netboot users with a remote filesystem over NFS (possibly over other networked filesystems). + + [Test cases] + 1) Boot a system with its root filesystem over NFS. + 2) Run 'sudo netplan apply' + 3) Validate that the system remains responsive and keeps connectivity over the same IP address as it had. + + [Regression potential] + This SRU changes network properties, and enforces that networkd does not release and re-request an IP address from DHCP when it is restarted. Environments relying on the IP release/renew behavior may find themselves staying on the previous IP address, which might negatively impact connectivity. Changes in connectivity on a system running netplan should be investigated as a potential regression from this SRU. Other regression possibilities would include failure to get a new IP address over time (usually seen as losing connectivity) or possible IP conflicts on a network. + + --- + With a system booted on the network, with its remote root fs on NFS: Running 'netplan apply' restarts systemd-networkd, which releases the IP received from DHCP. With no IP (and and IP potentially changing), the NFS server can't be reached so the system hangs. 'netplan apply' or restarting systemd-networkd should not affect teh system, it should continue working normally despite "changing" network states, as long as the effective IP remains the same.
