We should then fix that. We should be able to manage to get chrootless
working.

I don't think the required packages should need anything that chrootless
can't do. Even the hurd package now doesn't, with xattrs :)

Such commands look at their argv[0].

It's startup (before init) that handles the boot, and the message above
is what unmounts the filesystem. Do you see the "done" word on that
line?

Thanks for working on it :)
We had discussed about it with Helmut at debconf, and subhurd is
definitely the way for this :)
