[Bug 326216] Re: pdebuild host --debbuildopts inherited by target pbuild

As asked before: It would help us a lot if you could test it on a
currently supported Ubuntu version. When you test it and it is still an
issue, kindly upload the updated logs by running apport-collect 326216
and any other logs that are relevant for this particular issue.

Title:
  pdebuild host --debbuildopts inherited by target pbuild

Status in “pbuilder” package in Ubuntu:
  Incomplete
Status in “pbuilder” package in Debian:
  Confirmed

Bug description:
  Binary package hint: pbuilder

  This is a latent bug, exposed as a by-product of the fix I created for
  bug #278213 "Does not accept multiple --debbuildopts options" which
  resulted in "pbuilder (0.181ubuntu6)".

  The problem is that when using pdebuilder and passing --debbuildopts
  to both 'sides' (host and target), the target pbuilder dpkg-source
  incorrectly inherits the host --debbuildopts.

  For example:

   HOST_DEB_OPTIONS="--debbuildopts -i -I" 
   PBUILDER_DEB_OPTIONS="--debbuildopts -Idebian/dpkg-source.excludes"
   pdebuild --logfile $LOGNAME ${HOST_DEB_OPTIONS} -- ${PBUILDER_DEB_OPTIONS}

  results in the inner dpkg-source seeing:

   dpkg-source -i -I -Idebian/dpkg-source.excludes -b kvm-83+dfsg

  Which in Hardy and later isn't a problem (since -I is acceptable to
  dpkg-source >= v1.14.7). However, if working on back-porting a package
  to Gutsy or Feisty or Edgy the versions of dpkg-source in those
  releases do not understand the -I option without a file specification
  (-I<exclusion.list>).

  This will cause the target pbuild to fail since the source can't be
  extracted.

  This wouldn't have come to light if it wasn't for my desire to back-
  port some packages for use on long-lived servers that are running
  stable older releases. In these cases my build_test script generates
  two different sets of --debbuildopts for the host (more recent) and
  target (older) dpkg-source.

  The builds were failing and as can be seen in the example above it is
  because the host's --debbuildopts are passing to the target.

  Patches to follow.
