Title:
  dpkg-source failed to rename file across filesystems

Status in “dpkg” package in Ubuntu:
  New
Status in “dpkg” package in Debian:
  Fix Released

Bug description:
  Binary package hint: dpkg

  dpkg-source uses rename() perl function which fails when target is
  located on another file system. For example, prevu executes it as
  `dpkg-source -x -sn file.dsc /var/dest/dir`. On my computer /var
  resides on separated file system which leads to error if file.dsc not
  under /var:

  $ prevu libccrtp_1.7.1-2.dsc

  dpkg-source: extracting libccrtp in /var/cache/prevu/src/20157/extracted
  dpkg-source: info: unpacking libccrtp_1.7.1.orig.tar.gz
  dpkg-source: failure: Unable to rename /tmp/test/libccrtp_1.7.1.orig.tar.gz.tmp-extract.AXkZ7/ccrtp-1.7.1 to /var/cache/prevu/src/20157/extracted.orig: Invalid cross-device link

  This particular failed rename() is in
  /usr/share/perl5/Dpkg/Source/Archive.pm file, but you can grep through
  pm modules to find out more. perlfunc(1) suggests to use File::Copy
  module or mv utility instead of rename function to handle move across
  different file systems.

  I'm using dpkg 1.14.20ubuntu6 from Intrepid.
