 well... they could focus on GuixSD... or they could focus on *not*
doing GuixSD (at all, because half the stuff won't work) and instead
do linux kernel development.  if they'd said, "we're linux kernel
developers, we'd like to focus on improving mainling Allwinner A20
functionality so that OSes like GuixSD have 100% full functionality
for our users" i would have said, "great, here's the link to the
mainline linux-sunxi page"...

I knew that very well, that's my homepage ;-)
Waiting for HDMI / H3 also...

But your advocating people to continue to work on ultra-obsolete versions
(security-wise, etc) instead of pushing people to work on upstream is what
I found kind of strange.

But that's my personal opinion, and you're right to chose what's best for
the eoma project. We may not have the same priorities.

No harm intended

Looking at http://linux-sunxi.org/Linux_mainlining_effort , I see that
HDMI is listed as "in linux mainline since 4.15". Yey!

LVDS is still listed as "WIP" and VGA and CVBS are still listed as red
no-s, and VE (Video Engine) is listed as WIP.

 i've only got around six or seven available of the 2.7.4 units, or
thereabouts.  i need to keep two, one as a backup in case one gets
damaged (it happens).

 one way round that would be to use a VPN (i run one), set up the unit
at one location and rsync packages over to it for testing in a chroot
environment on the card.  it'll... need a little coordination :)

 or, i could in theory set up one of the two i need to keep hold of
here in TW and leave it switched on 24x7?

 yehyeh.  the way i do different OSes is simply replace the root
filesystem partition on pre-existing micro-sd cards.  i'll make sure
to include something (debian/testing armhf most likely - just don't do
"apt-get update" on it as it will pull in a shed-load of stuff that's
been done over the past... 2, 2.5 years)

 nope, not at all.  it's still the only available version of the linux
kernel that has 100% proven, finished and *working* support for *all*
functions of the Allwinner A20 processor.

 if you don't want or don't need HDMI, don't want video support, or a
shed-load of other functionality, feel free to use mainline linux
kernel source.

 great!  let's take a look...
https://lists.gnu.org/archive/html/guix-devel/2016-07/msg00515.html
ha!  looks like someone's been working on porting GuixSD to ARM
already.  it shouuuld be an extremely straightforward task if you're
prepared to stick with the known / tried-and-tested 3.4.104+
linux-sunxi kernel and the known tried-and-tested u-boot.

 superb.  feel free to contact me off-list, with an address and
telephone number i can put on the EMS TW Postal Service docket.
