slack: cannot execute /etc/rc.d/rc.0 or rc.6

[mschievano]

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

shutdown now -h

sending kill all...
cannot execute rc.0

:master:

rc.6

#! /bin/sh
#
# 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.
