the 127.0.0.1 new hostname mapping to the /etc/hosts list. However, it does not handle the case where the file does not exist, resulting in the hostname not being updated in /etc/hosts. When /etc/hosts is missing, it causes the sudo command to be blocked for a while and displays an "unable to resolve host" error message. This patch adds a workaround in hostname-config.sh to create a default /etc/hosts if it does not exist, ensuring the hostname is updated properly. Signed-off-by: gord_chen <[email protected]>
