This is a list of things I need to do. This is currently quite coarse,
I'll refine it incrementally.
- Make Debian/Hurd boot correctly using /etc/rcS.d/S*
- Keep its current init, runtty, /etc/hurd/* scripts and
the scripts from /etc/rcS.d.
- Trim the scripts in /etc/hurd/* not to do any initialization
that is (now) done by /etc/rcS.d/S*.
- Fix any issues encountered so far.
- Fix ifupdown.
- Use sysvinit`s init. Get rid of `runtty, /etc/hurd/*.
