[Bug 1361902] Re: 14.04 /etc/network/interfaces is always overwritten by Preseed

[Launchpad Bug Tracker]

This bug was fixed in the package netcfg - 1.119ubuntu1

---------------
netcfg (1.119ubuntu1) utopic; urgency=medium

  * Resynchronise with Debian.  Remaining changes:
    - Set default hostname to 'ubuntu'.
    - Set priority for get_domain to high for static configurations.
    - Set priority for get_domain to medium for non-static configurations.
    - Use 'auto <interface>' for all interfaces, dropping allow-hotplug
      which doesn't work with current udev.
    - Set DHCP and DHCPv6 timeout to 30s.
    - Use isc-dhcp-client-udeb on all architectures.
    - Flush all addresses and routes before configuring interfaces
      (LP: #848072)
    - Don't copy /etc/resolv.conf to target if resolvconf is installed.  (We
      already write resolvconf configuration to /etc/network/interfaces.)
    - Add a post-base-install hook to detect resolvconf and copy
      /run/resolvconf/resolv.conf to outside the target so that when /run is
      bind-mounted DNS resolving continues to work. (LP: #926447)
    - Apply patch from Alec Warner making netcfg respect
      netcfg/dhcpv6_timeout and running dhclient in one-shot mode (-1).
      (LP: #917905)
    - Fix FTBFS by checking the return value of fgets and fscanf.
    - Fix nm-conf to generate a valid NetworkManager static configuration
      file.

netcfg (1.119) unstable; urgency=medium

  * Don't copy /etc/network/interfaces to /target if
    netcfg/target_network_config=ifupdown; it's already been copied by the
    base-installer hook earlier, and copying it again makes it hard to
    modify /target/etc/network/interfaces in a preseed file (closes:
    #709017, LP: #1361902).
  * Fix BOOTIF detection to handle the newline at the end of a line read
    from /proc/cmdline (LP: #1350302).

  * Estonian (et.po) by Mattias Põldaru

netcfg (1.118) unstable; urgency=high

  * Fix support for entering an ESSID manually, it was previously
    getting ignored (Closes: #757478). Thanks to James Cowgill for the
    report and the patch!

netcfg (1.117) unstable; urgency=low

  * Add lintian overrides for untranslatable debconf templates. I like
    when packages are lintian-clean...

Title:
  14.04 /etc/network/interfaces is always overwritten by Preseed

Status in “netcfg” package in Ubuntu:
  Fix Released

Bug description:
  
  I'm having trouble with my /etc/network/interfaces file that is
  overwritten by every Preseed install.

  I have found out that when I let the late_command crash and I manually
  enter some identifier in:

  /etc/network/interfaces

  and

  /target/etc/network/interfaces

  the one in /etc/network/interfaces stays there, so no overwriting from
  the target version in that case.

  the fix to place the following in the late_command doesn't fix it
  either:

  cp /target/etc/network/interfaces /etc/network/interfaces

  Any idea on how to fix this ?
