Bug#196021: Order of package names in argument list shouldn't be relevant
Package: apt
Version: 0.5.4
The order of packages in argument list is relevant, how apt builds its
dependency tree. Here is an example:
mpiat0201:~# apt-get -u install nvidia-glx nvidia-glx-dev
nvidia-kernel-2.4.20.9.p4
Reading Package Lists... Done
Building Dependency Tree... Done
The following extra packages will be installed:
nvidia-kernel-2.4.20.9.athlon
The following NEW packages will be installed:
nvidia-glx nvidia-glx-dev nvidia-kernel-2.4.20.9.athlon
nvidia-kernel-2.4.20.9.p4
0 packages upgraded, 4 newly installed, 0 to remove and 1 not upgraded.
Need to get 0B/3464kB of archives. After unpacking 10.7MB will be used.
Do you want to continue? [Y/n] n
Abort.
Because nvidia-glx depends on a meta-package (nvidia-kernel), which is
provided by nvidia-kernel-2.4.20.9.athlon and nvidia-kernel-2.4.20.9.p4
it chooses to install the unwanted .athlon package, because the
requested .p4 package is at the end of the argument list.
mpiat0201:~# apt-get -u install nvidia-kernel-2.4.20.9.p4 nvidia-glx
nvidia-glx-dev

The following NEW packages will be installed:
nvidia-glx nvidia-glx-dev nvidia-kernel-2.4.20.9.p4
0 packages upgraded, 3 newly installed, 0 to remove and 1 not upgraded.

Now apt doesn't select the .athlon package, because the .p4 packge is in
at the beginning of the argument list of the apt-get command line.
I think that both invocations of apt should have the same result.
