Public bug reported: The man page man 5 interfaces states:
By default, on a freshly installed Debian system, the interfaces file includes a line to source files in the /etc/network/interfaces.d directory. A freshly installed 17.10 system lacks this line (and therefore is unable to handle interfaces defined in interfaces.d) ProblemType: Bug DistroRelease: Ubuntu 17.10 Package: debian-installer (not installed) ProcVersionSignature: Ubuntu 4.13.0-16.19-generic 4.13.4 Uname: Linux 4.13.0-16-generic x86_64 NonfreeKernelModules: zfs zunicode zavl zcommon znvpair ApportVersion: 2.20.7-0ubuntu3.1 Architecture: amd64 CurrentDesktop: XFCE Date: Wed Nov 1 11:59:35 2017 InstallationDate: Installed on 2017-10-24 (8 days ago) InstallationMedia: Lubuntu 17.10 "Artful Aardvark" - Release amd64 (20171017.1) MachineType: To Be Filled By O.E.M.
