1. il file rc.6 non esisteva (chissà dov'è finito) e al suo posto c'era rc.6.old
2. ho copiato rc.6.old su rc.6 e ci ho dato un occhio. mi sembra ok
3. rc.0 è un ln -s di rc.6 (ed è quindi lo stesso file)
=> il computer non si spegne
codice:
sending kill all...
cannot execute rc.0

# rc.6 This file is executed by init when it goes into runlevel
# 0 (halt) or runlevel 6 (reboot). It kills all processes,
# unmounts file systems and then either halts or reboots.
