Hello,

I noticed that with console-kit-daemon started, each time I switch to
another console, it writes its state to disk.  This limits a lot the
possibility to save laptop power while e.g. reading documentation over
several consoles.  Couldn't consolekit rather write its status to a
memory-backed FS, like /lib/init/rw?

It's a log file which is meant to be kept during reboots (and e.g. used by
ck-history) so writing to a tmpfs is not a good idea.
The use case you are mentioning also sounds a bit artificial.
Usually when you switch consoles you are triggering reads/writes anyway.

Thus I'm marking the bug as wontfix

What for?
Can that somehow be disabled?

?!?! I'm very often reading documents or source code in the train, and
for that no read/writes are needed once everything is in cache.

Hello,

My original concern is that "with console-kit-daemon started, each
time I switch to another console, it writes its state to disk.  This
limits a lot the possibility to save laptop power while e.g. reading
documentation over several consoles."

Apparently, this is a feature of console-kit-daemon and will not be
disabled.  I have found that it's hal which starts console-kit-daemon,
but I failed to find where that could be disabled.  Is there one (and
should thus be documented), or could it be added?

Oops, it's not actually hal but dbus which is at stake.

This feature is called dbus system activation [1].

I don't know of a documented way to disable a dbus activated service besides
removing its service file from /usr/share/dbus-1/system-services.

This obviously won't survive a package upgrade.

As dbus follows the xdg spec, you might wanna try to copy the service file to
/usr/local/share/dbus-1/system-services/ and set
Exec=/bin/false

This is an ugly hack though, so beware.
