Title:
RFC: replace linux-virtual with linux-server / tune kernel packages
Status in linux package in Ubuntu:
Incomplete
Bug description:
We currently build 2 meta packages for easy consumption and automatic
kernel upgrades. These are linux-virtual and linux-generic.
The -virtual meta package was created with the general purpose of
"support virtual environments", and then extended to include "and
common cloud workloads" (adding things like rdb and kvm).
Would it be possible to find a happy medium where we had enough
drivers to enable network and block devices and essential server
devices but maintained a reasonable install size ? That would enable
us to create one set of images for use in cloud enviroments be they on
bare metal or hypervisors.
As an example of sizes collected from a cloud image, we have:
release | kernel | apt inst| initrd | /lib/modules
vivid | linux-virtual | 125M | 8M | 34M
vivid | linux-generic | 358M | 27M | 193M
trusty | linux-virtual | 119M | 7M | 31M
trusty | linux-generic | 337M | 24M | 184M
'apt inst' is as reported by apt install after 'apt-get --purge ^linux-.*'
vivid version 3.18.0.11, trusty version 3.13.0.44.51.
both packages share the linux kernel binary which in this case is 5.6M on
trusty and 6.3M on vivid.
For a cloud image with default install in the 700M range, the
difference between -virtual and -generic is considerable. So it
clearly has its value.
However, this value comes at the cost of specialization. If a user
installs a server via MAAS or via ISO, they get linux-generic and have
some set of modules/kernel function. If they run a cloud image, they
have a different set. This is less than desireable as we'd like to
say that both cases are "Ubuntu Server". It also means that we have
to build "maas images" which are primarily "cloud images with a
hardware kernel".
