NAME
dpkg repack put an unpacked .deb file back together

SYNOPSIS
dpkg repack [ root=dir] [ arch=architecture] [ generate] packagename [packagename ...]

DESCRIPTION
dpkg repack creates a .deb file out of a Debian package that has already been installed on your system.

If any changes have been made to the package while it was unpacked (ie, conffiles files in /etc modified), the new package will inherit the changes. (There
are exceptions to this, including changes to configuration files that are not conffiles, including those managed by ucf.)

This utility can make it easy to copy packages from one computer to another, or to recreate packages that are installed on your system, but no longer avail
able elsewhere.

Note: dpkg repack will place the created package in the current directory.


OPTIONS
root=dir
Take package from filesystem rooted on . This is useful if, for example, you have another computer nfs mounted on /mnt, then you can use
root=/mnt to reassemble packages from that computer.


arch=architecture
Make the package be for a different architecture. dpkg repack cannot tell if an installed package is architecture all or is specific to the system's
architecture, so by default it uses dpkg print architecture to determine the build architecture. If you know the package is architecture all, you
can use this option to force dpkg repack to use the right architecture.


generate
Generate a temporary directory suitable for building a package from, but do not actually create the package. This is useful if you want to move files
around in the package before building it. The package can be built from this temporary directory by running "dpkg build", passing it the generated
directory.


packagename
The name of the package to attempt to repack. Multiple packages can be listed.


BUGS
This program accesses the dpkg database directly in places, querying for data that cannot be gotten via dpkg.


There is a tricky situation that can occur if you dpkg repack a package that has modified conffiles. The modified conffiles are packed up. Now if you install
the package, dpkg does not realize that the conffiles in it are modified. So if you later upgrade to a new version of the package, dpkg will believe that the
old (repacked) package has older conffiles than the new version, and will silently replace the conffiles with those in the package you are upgrading to.


While dpkg repack can be run under fakeroot and will work most of the time, fakeroot u must be used if any of the files to be repacked are owned by non root
users. Otherwise the package will have them owned by root. dpkg repack will warn if you run it under fakeroot without the u flag.
