[Message part 1 (text/plain, inline)]

Hi,

Gsettings-desktop-schemas is required by WebKitGTK to load HTTPS pages.
But it also depends on gnome-backgrounds which weights some 40 MiB.

For sure this does not help the closure size...

I suggest we create a separate output, or maybe a
gsettings-desktop-schemas-minimal which does not include the reference
to the backgrounds.

Thoughts?

Pierre

There are only two schemes that contain a reference, so maybe those can 
be put in a separate output:

antipode <at> antipode ~$ grep -RF gnome-background 
/gnu/store/5nqkzrcgwbbk9lnfz73g1nidfp57szlm-gsettings-desktop-schemas-41.0/
grep: 
/gnu/store/5nqkzrcgwbbk9lnfz73g1nidfp57szlm-gsettings-desktop-schemas-41.0/share/glib-2.0/schemas/gschemas.compiled: 
binair bestand bevat de gezochte tekst

<default>'file:///gnu/store/cknaw49l7lnf2r6djvxjd8xvrzl6lcgn-gnome-backgrounds-41.0//share/backgrounds/gnome/adwaita-timed.xml'</default>
/gnu/store/5nqkzrcgwbbk9lnfz73g1nidfp57szlm-gsettings-desktop-schemas-41.0/share/glib-2.0/schemas/org.gnome.desktop.screensaver.gschema.xml: 
<default>'file:///gnu/store/cknaw49l7lnf2r6djvxjd8xvrzl6lcgn-gnome-backgrounds-41.0//share/backgrounds/gnome/adwaita-timed.xml'</default>

Two package variants is not ideal, because then one has to determine 
which one to choose, and people that use the background schemes would 
have extra disk usage because of the two copies of the other schemes 
(relatively tiny: 224K if the 36K gschemas.compiles is counted, 153K for 
apparent size).

As such, I'd prefer gong for a separate output. It would need to be 
checked that this doesn't cause problems from GNOME users though.

Greetings,
Maxime.

I think we can use some gsettings overrides in the gnome package, there
is no need for gsettings-desktop-schemas hardcode the background
setting itself.
