Prevent User Lockout

To prevent lock-outs after accidentially removing zsh (thanks to @fox34) (as explained in the wiki you can add a check for zsh and fallback to ash in /etc/rc.local:

# Revert root shell to ash if zsh is not available
if grep -q '^root:.*:/usr/bin/zsh$' /etc/passwd && [ ! -x /usr/bin/zsh ]; then
    # zsh is root shell, but zsh was not found or not executable: revert to default ash
    [ -x /usr/bin/logger ] && /usr/bin/logger -s "Reverting root shell to ash, as zsh was not found on the system"
    sed -i -- 's:/usr/bin/zsh:/bin/ash:g' /etc/passwd
