NAME

       jablicator - Share package collection choice across machines

SYNOPSIS

       jablicator [--root <path>]

DESCRIPTION

       jablicator  generates  an  "apt-get"-able  package.  The package itself is empty. However it has a dependency for every non-required Debian
       package that is on the machine. This program will create and populate two directories dists and pool in your  working  directory.  You  can
       then move them to a web accessible location.

       This utility is designed to reduce software distribution and maintenance costs by reducing redundant system administration.  For example, I
       have spent a lot of time finding and vetting image processing software from Debian's large package collection. With this utility, my  image
       processing colleague down the hall can easily benefit from the fruit of my labor.

       There are many replication techniques in Debian. This one has the advantage of using the apt and dpkg infrastructure. A disadvantage is the
       possibility of packages changing out from under you in the Debian distribution (especially in testing or unstable). That means that  jabli-
       cator output can grow stale over time if it is not regenerated.

SECURITY

       The  packages produced by this program contain a lot of information, including a list of the Debian packages installed on the machine and a
       listing of apt-get sources. Some system administrators consider sharing such information a security risk.

FILES

       /etc/apt/sources.list

OPTIONS

       --root <path>
	      Being able to pull in package selections from another install can be helpful, in the cases of a non-functional  system,  or  reading
	      from  a  hard  drive install under Knoppix. In other words, source from a root filesystem that is not mounted at the root. This is a
	      rare situation and most users should not use this option.

SEE ALSO

       dpkg(8) apt-get(8).

DPKG-REPACK(1)						      General Commands Manual						    DPKG-REPACK(1)

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 available elsewhere.

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

OPTIONS

       --root=dir
	      Take  package  from  filesystem rooted on <dir>. 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  spe-
	      cific 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.
