I have not tested this yet, but it sounds like good news for the a11y
perspective and those who struggled with the colours on the aubergine
accessible installer

It would probably be better to add new values for the existing
FRONTEND_BACKGROUND environment variable (which can also go on the
kernel command line) rather than inventing a new preseeded template
which would basically just be a synonym for it.
Great idea, Colin. I have this now working, with an upload of
cdebconf-0.154ubuntu2 to Natty archive. This will not make Beta1, but
should absolutely land in Beta2, and will need release-team approval.
Note that it will also require a re-spin of debian-installer. I'm
tracking this in Bug #730672. There's a debdiff for cdebconf there.
As of that upload, any user of the text installer will be able to
optionally specify a FRONTEND_BACKGROUND value on the kernel command
line. The cdebconf-newt-udeb package provides the following:
* dark -- high contrast, accessibility theme
* original -- the traditional, legacy newt theme
* ubuntu -- the aubergine theme (basically, s/blue/magenta/g)
These are installed to:
* /etc/newt/palette.dark
* /etc/newt/palette.original
* /etc/newt/palette.ubuntu
By default, there is a symlink installed by cdebconf-newt-udeb in the
ISO filesystem:
* /etc/newt/palette -> /etc/newt/palette.ubuntu
At debian-installer/cdebconf initialization of the newt frontend, if a
kernel parameter FRONTEND_BACKGROUND=<whatever> is found, then the
symlink at /etc/newt/palette is broken and replaced with a symlink to
/etc/newt/palette.<whatever>.
In this way, any derivative of Ubuntu can ship their own palette in a
udeb that's included in their ISO build, install that palette at
/etc/newt/palette.kubuntu, for example, and append
FRONTEND_BACKGROUND=kubuntu to the kernel parameters.
If you (or your Ubuntu derivative) just want the legacy behavior, then
don't bother shipping your own palette, but simply append
FRONTEND_BACKGROUND=original to the kernel parameters.
I hope this helps with your calls for reconfigurability! I've enjoyed
working with everyone on this ;-)
Cheers,
