control apt-get selection for packages having multiple virtual package alternatives
hi! let me explain with the example of xserver-xorg. amongst others it has dependencies of xserver-xorg-input-all and xserver-xorg-video-all but both dependencies can also be provided by the packages xserver-xorg-input-7 and xserver-xorg-video-6. as you all know, the difference is that the meta-packages of xserver-xorg-input-all and xserver-xorg-video-all will pull all video and input packages while the virtual packages of xserver-xorg-input-7 and xserver-xorg-video-6 allow only one of the drivers to be installed to satisfy the dependency. as a result apt-get install xserver-xorg-video-foobar will not install all video drivers and apt-get install xserver-xorg-input-baz will not install all input drivers. my problem now is, that when i do apt-get install xserver-xorg-video-foobar i will still get xserver-xorg-input all and when i do apt-get install xserver-xorg-input-baz i will still get xserver-xorg-video all. trying to resolv this by doing apt-get install xserver-xorg-video-foobar xserver-xorg-input-baz doesnt help and will still get the *-all package of input or video whichever is not mentioned first. so in the general case of having a package with several dependencies that are satisfied by either one *-all metapackage or one virtual package where i can select the package providing it - how do i tell apt to select the specific package i want in BOTH cases? and in particular: how do i do that for an installation of xserver-xorg without removing the unwanted packages later? cheers josch
