it'd be nice to have a --no-scripts flag

debdiff updated to include LP number

Looking at the attachments in this bug report, I noticed that "ifupdown_no_scripts.diff" was not flagged as a patch. A patch contains changes to an Ubuntu package that will resolve a bug and this attachment is one! Subsequently, I've checked the patch flag for it. In the future when submitting patches please use the patch checkbox as there are some Launchpad searches that use this feature. Thanks for your contribution Javier Uruen Val!

Thank you Javier for your patch, it would be great if you could forward the patch upstream for their take on this patch.

I don't think it's worth adding more Ubuntu delta for that patch but I'm sure Debian will consider taking it and we'll then benefit from it in 12.10.

This bug was fixed in the package ifupdown - 0.7ubuntu1

---------------
ifupdown (0.7ubuntu1) quantal-proposed; urgency=low

  * Resynchronise with Debian experimental. Remaining changes:
    (LP: #298488, LP: #663352)
    - ifupdown.nw: Use 100 as default route metric unless an explicit metric
      parameter is set in /etc/network/interface.
    - If the /etc/NetworkManager/NetworkManager.conf file is present
      but doesn't have the "ifupdown:managed" the previous upload instructed
      the iniparser to return -1, which evaluates to TRUE. We instead instruct
      it to return 0, as we shouldn't prevent ifupdown from managing the
      interfaces in that case, as NM won't either. (LP: #281984)
    - debian/postinst: If the loopback interface is missing from the config
      in /etc/network/interfaces, add it on upgrade.
    - Add jobs and hooks for upstart.
  * Cherry-pick commit 011d5904c09d from upstream, fixing cases where the
    error messages wouldn't be triggered (caused test failure).
  * Cherry-pick commit 7c1a226cc995 from upstream, adds support for two
    options on dhcpv6 (accept_ra and autoconf) (LP: #1013597)
  * Cherry-pick commit 5af7e814faee from upstream, fixing a failure in the
    example script generate-interfaces.pl (LP: #286808)
  * Cherry-pick commit a1f8efc4d93f from upstream, add --no-scripts as a
    parameter to ifup/ifdown, allowing the user to bypass the the scripts
    in /etc/network/if-*.d/ (LP: #258782)

ifupdown (0.7) unstable; urgency=low

  * Accept duplicate options in /etc/network/interfaces, join them using
    a newline as a delimiter.
  * If an interface isn't defined, but mentioned in auto or allow statement,
    don't mention it in ifquery output.
  * Change shortcut for --exclude to -X (was -e previously).
  * Make ifquery return false if the interface isn't defined.
  * Fix typos in the changelog.
  * Calculate broadcast address internally.
  * Allow concurrent netmask specification in both address (using CIDR
    notation) and netmask for IPv6 (Closes: #674775).
  * Add preferred-lifetime setting for IPv6.
  * Pass -w and -e options to sysctl so we still can configure an interface
    even if IPv6 SLAAC options can't be set for some reason.
  * Port to GNU/Hurd (thanks to Svante Signell, closes: #296115).
  * Chdir to root when executing external programs (Closes: #361964).
  * Remove updetach from PPP method (Closes: #675016).
  * Configure hotplug interfaces only if they're running (thanks to Evgeni
    Golov, closes: #673658).
  * Rewrite NEWS file (Closes: #673688).
  * Update examples (Closes: #340992).
  * Update tests.
  * Update README.

ifupdown (0.7~rc3) unstable; urgency=low

  * Upload to unstable.
  * Don't refer to README from netbase any more.
  * Internal changes:
    - Make set_variable() able to set variables conditionally.
    - Improve conversions interface.
    - Add some support for interface link configuration.
    - Don't leak memory in some functions.
  * Configure VLANs automatically (Closes: #520436).
  * Calculate netmask internally, so even if a user haven't supplied
    one or have used CIDR notation, hook scripts will have it properly
    specified in IF_NE...
