How to remove a particular package or packages collection for an image

How to remove a particular package or packages collection for an image

Hi,

I am using Yocto milestone release 1.1.1 for my custom root filesystem
image creation. I just need some help in achieving it successfully.
I wrote a custom task bb file which defines/includes the packages i need in
my image. I also wrote a core-image-custom.bb file that includes these
tasks + other tasks. I also inherited core-image.bbclass in
core-image-custom.bb.  The file looks something like this,

*IMAGE_INSTALL = "\*
*    task-base \*
*    task-core-basic \*
*    task-core-boot \*
*    .......*
*    task-custom \*
*    "*
*inherit core-image*

I did  dry-run on core-image-custom and I see mostly all packages from
yocto included in my image, the packages that I do not need. So, how can I
remove a particular package or a package collection, say graphics or some X
packages for my image. Is it possible? or can core-image.bbclass is
overwritable? Does my approach ok?

Any help in achieving this is much appreciated.

Thanks,
JC

The basic package selection in the Poky/Yocto images is done on basis of
the DISTRO_FEATURES variable, so you need to set this somewhere suitable
to only include the components you need (iirc, the default package
selection is quite rich).

Other than that, bitbake -g <package> generates .dot files that show
package dependencies, so you can work out why particular package is
being included.
