Package: apt
Version: 0.7.11
Severity: normal
apt-get (and aptitude) needs an option for only installing hard
dependencies. That is, those dependencies that must be satisfied or
the package can't work. Something like --no-recommended.
I consider this a bug, not merely a wishlist item, because:
* Current apt install not only the needed extra packages, but
"recommended" but not really necessary packages as well.
This is easy to see as the unwanted packages can be removed
later without also removing the package I wanted.
* This is a problem when installing small embedded machines. The
current workaround is to delete all unwanted packages later,
but that is cumbersome when a single apt-get may pull in
a couple of unneeded packages that depends on 20-30 other
unwanted packages. And it is a waste of bandwidth and time too.
Example:
I installed a machine that is mostly a router, but it also runs gpsd
so I can see where it is.
Unfortunately, installing "gpsd" pull in "gpsd-clients", which has
dependencies on x11-common and a whole lot of other X-related packages.
But this machine does not run X! So I had to delete all those packages
manually later. And so on for some other software as well, and so on
when upgrading . . .
Now, I understand that most people will want gpsd-clients along with
gpsd, so having this as default behaviour is fine with me. But
having the ability to do
"apt-get install --no-recommended gpsd" and _only_ get gpsd and libgps17
would be ideal.
Another possible workaround that avoids bandwith wasting is to
download packages one by one and install using dpkg. That is very
cumbersome for packages that has many dependencies - exactly the reason
for having "apt" in the first place.

Did you check the manual? This feature was added years ago, quoting
from the manual:
-R, --without-recommends
Do not treat recommendations as dependencies when installing new
packages (this overrides settings in /etc/apt/apt.conf and
~/.aptitude/config). Packages previously installed due to
recommendations will not be removed.
This corresponds to the pair of configuration options
Apt::Install-Recommends and Aptitude::Keep-Recommends.
-r, --with-recommends
Treat recommendations as dependencies when installing new packages
(this overrides settings in /etc/apt/apt.conf and
~/.aptitude/config).
This corresponds to the configuration option
Apt::Install-Recommends
You have the default configuration:
> APT::Install-Recommends "1";
> APT::Install-Suggests "0";
Just add the following line in /etc/apt/apt.conf or in a separate file
under conf.d and that's all:
APT::Install-Recommends "0";
BTW, if you disable the installation of recommends you should expect
that some software does NOT work out of the box. Don't do this unleas
you know what you're doing!!
Thanks
