Subject: [PATCH] cloud-init: Change order of entries in /etc/hosts
|
|
|
|
The Alpine /etc/hosts template results in a file where the long form of
|
|
names (including localhost) come before the short form. This means that
|
|
when running tools like 'netstat' and 'ss' which convert IP address to
|
|
names that their output will show 'localhost.localdomain' rather than
|
|
'localhost.' This patch swaps the order of the short and long form names
|
|
so such utils will show the short form name.
