Le modifiche al grub ti fanno partire bootchart all'avvio, bootchart serve per misurare i tempi di avvio, qua la wiki:
Modifica la riga demoni in rc.conf da:
DAEMONS=(@hwclock @syslog-ng dbus network netfs crond gdm @sensor)
a:
DAEMONS=(hwclock syslog-ng dbus @gdm @sensor @crond @network @netfs)
Per la parte di rete si potrebbe anche commentarla tutta con # e demandare tutto al gestore di rete, ormai il suggerimento (ed il futuro andazzo) è quello.
Per inittab ho modificato i wait in once e tieni solo 2 terminali:#
# /etc/inittab

# Runlevels:
# 0 Halt
# 1(S) Single-user
# 2 Not used
# 3 Multi-user
# 4 Not used
# 5 X11
# 6 Reboot
