I have written a workaround for any of the various "no recovery shell" bugs.
It's not perfect as you have to reboot in single-suer mode to use it(and again
for a root filesystem error correction), but it allows you to recover without
booting from another device. It looks for the word "single" on /proc/cmdline,
and if it is present stops mountall, opens a recovery shell, and restarts
mountall on exiting the shell. It basically does what mountall-shell.conf would
do if it caught the stopped mountall signal.
Cut and paste the text below, save it as "recovery-shell.conf" and drop
it into /etc/init .
# Recovery shell-opens shell BEFORE Mountall starts

failed boots"
start on startup
task
console owner
script
if test $(grep single /proc/cmdline | head -c 4) ; then
initctl stop mountall
usplash_write "QUIT"
setupcon
echo "A Root Shell will now be started for recovery."
sulogin
exec start --no-wait mountall
fi
end script
