A quick follow-up: Starting an ssh daemon in initramfs was complicated, in particular, once the real root filesystem is set, the connection becomes useless (see switch_root in /usr/share/initramfs-tools/init). In fact, it is possible to start a terminal, and it is quite easy, by adding a script in /etc/init.d/ that will start the terminal and use rc.d to schedule it soon enough: /etc/init.d/rescueterm.sh: #! /bin/sh ### BEGIN INIT INFO # Provides: rescueterm # Required-Start: keyboard-setup # Required-Stop: # Should-Start: # Default-Start: S # Default-Stop: # X-Interactive: true # Short-Description: Start a console on tty8 without using inittab ### END INIT INFO PATH=/sbin:/bin:/usr/bin . /lib/lsb/init-functions case "$1" in start|"") log_begin_msg "Starting rescue terminal" # openvt is used because it's not blocking, while getty is. LOGIN_TIMEOUT=0 openvt -c8 login log_end_msg ;; restart|reload|force-reload) echo "Error: argument '$1' not supported" >&2 exit 3 ;; stop) # No-op ;; *) echo "Usage: rescueterm.sh [start|stop]" >&2 exit 3 ;; esac : and enable it: update-rc.d rescueterm.sh enable S (if there is a better way to embed code on the list, don't hesitate to tell me...!)
