= Proposed System Wide Change: Smaller Cloud Image Footprint =
Change owner(s): Sandro Mathys <red at fedoraproject.org> & Cloud SIG
Shrink the footprint of our cloud images as far as reasonably, and within the
given timeframe, possible.
== Detailed Description ==
Space is precious in the cloud, therefore the Cloud SIG tries to keep the
images' footprint as small as reasonably possible. Several approaches are
ongoing in this regard and while they are hardly worth mentioning
individually, the combined effort is going to be noticeable.
== Scope ==
As mentioned, there's really various changes that are quite independent of
each other but share the common goal.
* Proposal owners:
** Replace NetworkManager, etc. with systemd-networkd.
** Make sure only just kernel-core, not kernel and kernel-drivers, is
installed (see the related change: Modular Kernel Packaging for Cloud ).
** Make sure only the packages really required are installed.
** Use %packages --excludedocs to to skip installing docs.
** Use %packages --instLangs= to ship only just English.
** Tweak the locales (in %post) so that local-archive ships with only just
English instead of all languages. We might skip this one if it seems too much
tinkering. Work is going on to have proper support for this in the glibc
package (see rhbz#156477  - also, c#30 shows the necessary tinkering).
* Other developers:
** Packages that are part of any cloud image (and in the long run all
packages) must use %license instead of %doc for the license file(s) so we can
skip shipping docs but still ship licenses. (See separate change Use license
macro in RPMs for packages in Cloud Image 
** cloud-init should no longer require python-cheetah and needs to be
refactored (upstream) accordingly.
* Release engineering: Nothing.
* Policies and guidelines:
** Packaging Guidelines need to reflect that license files must be tagged with
%license instead of %docs (FPC#411 ).
