   Just for reference:

Package description page:
http://packages.debian.org/squeeze/util-linux

Original upstream sources Debian are using:
http://ftp.de.debian.org/debian/pool/main/u/util-linux/util-linux_2.17.2.orig.tar.gz

Debian patches on top of that source (mostly to the build system):
http://ftp.de.debian.org/debian/pool/main/u/util-linux/util-linux_2.17.2-5.diff.gz

   Hugo.
