Yeah, this is maybe the 3rd time I've been on IRC, I guess I've given
up trying to get it to work on my phone. Some of it's interesting

Page 8, "Fig. 1-1 RK805 One Battery Cell Application" is what I meant.
I suppose it's possible it works but most people don't use it so it
isn't well documented. Even in fig 1-1 I can't tell where the battery
is.
It has a sleep mode and an alarm. Page 19 (by xpdf) shows registers
for seconds, minutes, hours, etc. More on page 21-26.
I searched the IRC for battery and found:

<tl_lim> I can provide circuit how to add 3V battery power to existing
schematic for RTC power

<Xalius> the white connector is for the RTC battery
I would assume this battery is for a ups like function.
And I just noticed something about the armbian release of stretch
available on the pine site. The initial login is as root, meaning one
can probably addusr his own named account as user 1000. This would
solve several problems I believe, so I have that image coming in now,
and if I have time later today I'll burn it to an sd card and give it a
shot. It can't be any worse of a C.F. than the ayufan builds with its
pre-allocated user 1000.
Although having a preallocated user 1000 is the standard "Debian Way",
the objective being that you can telnet (later SSH) in using that user
and then sudo su to get root (fouled up on some versions that don't
add user 1000 to sudoers). For quite a long time you've only been able
to login as root from the system console (i.e. the directly-connected
keyboard and screen) and I think in at least some cases (display manager
specific) you can't get to a GUI as root: you have to do a
<Ctrl><Alt><F1> etc.
You can change whether root can get a GUI from system-specific display
manager configuration. You can change whether you can SSH in as root in
SSH configuration files. I've not seen a situation on Debian- but have
on Solaris- where one has to muck around with PAM to change this, which
TBH is a fairly common requirement during system setup.
