Yes, but the point is getting org-mode to run on android.

I propose we add [Android] as a cookie to the subject lines, so people
can filter them.

I see. I didn't look at the changelog for the page ;)

Ok.

A small update, I'm not done yet:

I have emacs + org-mode running now, but it's very slow. Emacs on
its own runs and starts quite fast, but as soon as I add my whole
config, it takes 90 seconds to start, and 30 seconds to change in the
org-mode agenda from one day to another.

As 30 seconds are way too long, I'm obviously going to try cut down my
config and maybe just use a subset of my org-files on the phone.

If I can't that last figure below 5 seconds I think the experiment is
going to be called off as a failure. (Or maybe I'll just use the local
emacs as an emergency fallback if I have no network access.)

Apparently some system administration tasks on the debian installation
take so much memory that the whole system gets unstable, because the
oom killer is going to kill important services. I just had to reboot
my phone after generating a UTF8 locale. I looked at adb logcat and
the android core was very unhappy and killed every service it could
find, even the phone service... So I probably want to make sure I
don't need to use my phone when administrating the debian
installation.

The debian installer uses a loopback mount, as it doesn't require a
native ext filesystem. This is probably handy, but I guess most root
mods these days use an ext partition anyway, so why not just use
that...
