Extracting/RePackaging Deb Package
Here is the original absolute file paths for a working deb package called
blah-amd64.deb:
Code:
dpkg-deb -c blah-amd64.deb |less
drwxr-xr-x root/root         0 2014-12-02 09:48 ./
drwxr-xr-x root/root         0 2014-12-02 09:48 ./usr/
drwxr-xr-x root/root         0 2014-12-02 09:48 ./usr/share/
drwxr-xr-x root/root         0 2014-12-02 09:48 ./usr/share/applications/
-rw-r--r-- root/root       301 2014-12-02 09:48 ./usr/share/applications/blah.desktop
drwxr-xr-x root/root         0 2014-12-02 09:48 ./usr/share/blah/
-rw-r--r-- root/root     17408 2014-01-21 16:53 ./usr/share/blah/blah.1

I extract it via:
Code:
dpkg-deb -x blah-amd64.deb .
dpkg-deb -e blah-amd64.deb ./DEBIAN

which extracts it to the current directory called
Code:
usr/

I make my modification to my file:
Code:
usr/share/blah/blah.1

and when I repackage blah-amd64.deb via:
Code:
sudo dpkg-deb -b . blah-amd64.deb

and look at the absolute paths:
Code:
dpkg-deb -c blah-amd64.deb |less
drwxr-xr-x root/root         0 2014-12-02 09:48 ./
drwxr-xr-x root/root         0 2014-12-02 09:48 ./applications/
-rw-r--r-- root/root       301 2014-12-02 09:48 ./applications/blah.desktop
drwxr-xr-x root/root         0 2014-12-02 09:48 ./blah/
-rw-r--r-- root/root     17408 2014-01-21 16:53 ./blah/blah.1

it changes the path to "/". I want to repackage it back to its original location so when the package is installed, it will install it in the correct path which is /usr/share/blah. Can someone shed some light on what is going on?

deb-old

deb-old(5)							    dpkg suite								deb-old(5)

NAME

       deb-old - old style Debian binary package format

SYNOPSIS

       filename.deb

DESCRIPTION

       The  .deb  format  is the Debian binary package file format. This manual page describes the old format, used before Debian 0.93. Please see
       deb(5) for details of the new format.

FORMAT

       The file is two lines of format information as ASCII text, followed by two concatenated gzipped ustar files.

       The first line is the format version number padded to 8 digits, and is 0.939000 for all old-format archives.

       The second line is a decimal string (without leading zeroes) giving the length of the first gzipped tarfile.

       Each of these lines is terminated with a single newline character.

       The first tarfile contains the control information, as a series of ordinary files. The file control must be present,  as  it  contains  the
       core control information.

       In  some  very  old  archives,  the  files  in  the  control  tarfile  may optionally be in a DEBIAN subdirectory. In that case, the DEBIAN
       subdirectory will be in the control tarfile too, and the control tarfile will have only files in that  directory.  Optionally  the  control
       tarfile may contain an entry for '.', that is, the current directory.

       The second gzipped tarfile is the filesystem archive, containing pathnames relative to the root directory of the system to be installed on.
       The pathnames do not have leading slashes.
