Depends. If you want to do it for all Debian systems, that'll require
patching boot-floppies, doing lots of compatability code to upgrade
existing installs without breaking things, and so forth. If you just
want to do it for your systems, or even make it an option that people
can easily choose at install, that's easier.

We don't have tmpfs compiled in, / is read-only. I'm sorry, maybe I wasn't
clear:

	rmdir /run
	ln -s /var/run/early /run

> just have /run as a symlink to /var/run 

It'd be safer to keep the namespaces separate, IMO.

Note that there's nothing stopping *you* from setting up /mem as a tmpfs,
and linking /var/run, /var/log, /run and so forth to it, and preserving
them on reboot (or backing them up from cron) as you feel appropriate.

We could, I think, start using /run today, by:

	(a) adding it as a directory to sysvinit
	(b) arranging it to be cleared in early startup scripts

Cheers,
