Ian Wienand e443700b5c Formalise saving of /etc/resolv.conf ... systemd-resolved has a new behaviour in bionic, in that if there is no /etc/resolv.conf file when it installs, it assumes it is a fresh system and makes /etc/resolf.conf a symlink into its compatability files. dib ends up saving & restoring whatever /etc/resolv.conf we have after the inital chroot creation, which may not be what we want -- in the above case it restores the system-resolved symlink. For openstack-infra, we use unbound and want simply "127.0.0.1" in a /etc/resolv.conf file [1]. Formalise the ability to save specific contents into the final image. Add documentation, and a note in the code that it's an external interface. I would have preferred to namespace the .ORIG file with DIB_ or similar, but this unofficial interface has already escaped into the wild. Leave it as is for simplicity. [1] Note that systemd-resolved will obey /etc/resolv.conf as you would expect, if file exists. Change-Id: Ie0e97d8072e2b21a54b053fa6fb07b62960c686d		2018-04-04 15:17:45 +10:00
