Meta-Pkgs
Pursuant to UDS-Q blueprints, the Ubuntu Kernel Team team has collapsed multiple 12.04 x86 flavours into a single 12.10 flavour, i.e. generic. We've also modified kernel packaging for x86 such that it is delivered in 2 packages, i.e. linux-image and linux-image-extra. This accommodates the needs of virtual instances where the smallest possible kernel package is desired, i.e. linux-image. With these changes in flavors, there are also corresponding changes to the meta packages which support these flavors. The following documents the changes to the meta package offerings.
Quantal Quetzal 12.10
For the documented list of supported 12.10 kernel flavours, please see https://wiki.ubuntu.com/Kernel/Dev/Flavours
The general relationship rules for the Quantal kernel meta packages are as follows:
linux-<flavour> |
depends on linux-headers-<flavour> and linux-image-<flavour>. Note the dependency of linux-<flavour> on the appropriate kernel and headers package. This is now common across all architectures. |
linux-headers-<flavour> |
depends on the kernel headers package. |
linux-image-<flavour> |
depends on the kernel and extras binary packages. [1] |
[1] The exception is linux-image-virtual which only depends on the kernel binary package and not the extras package. Linux-image-extra-virtual depends on both the kernel and extras packages.
The specific Quantal kernel meta package mappings are as follows. Package flow diagrams have also been included below.
