NAME

     germinate-pkg-diff — compare seeds against currently installed packages

SYNOPSIS

     germinate-pkg-diff [-l file] [-m {i|r|d}] [-a arch] [seeds]

DESCRIPTION

     germinate-pkg-diff compares the expansion of a list of seed packages against the set of
     packages installed on the current system.  When constructing seeds for a software
     distribution, it can be used to iteratively find packages installed on developers' systems
     that should be included in the seeds.

     A list of seeds against which to compare may be supplied as non-option arguments.  Seeds
     from which they inherit will be added automatically.  The default is ‘desktop’.

OPTIONS

     -l, --list file
           Read the list of currently installed packages from file.  The default is to read the
           output of dpkg --get-selections, and any supplied file should be in the same format.

     -m, --mode {i|r|d}
           Set the output mode as follows:

           i     Show the dpkg selections needed to install just these seeds.  List unseeded but
                 installed files as “deinstall”, and seeded but uninstalled files as “install”.

           r     List unseeded but installed files as “install”, and seeded but uninstalled files
                 as “deinstall”.

           d     Show the differences between the packages specified by the seeds and the list of
                 installed packages, in a somewhat diff-like format.

     -S, --seed-source source,...
           Fetch seeds from the specified sources.  The default is
           http://people.canonical.com/~ubuntu-archive/seeds/.

     -s, --seed-dist dist
           Fetch seeds for distribution dist.  The default is ubuntu.bionic.

     -d, --dist dist,...
           Operate on the specified distributions.  The default is bionic.  Listing multiple
           distributions may be useful, for example, when examining both a released distribution
           and its security updates.

     -a, --arch arch
           Operate on architecture arch.  The default is i386.

BUGS

     --mode r is useless as dpkg --set-selections input.
