Ridurre servizi all'avvio (F18)

Fedora Linux Configurazione
#1

ciao,
quali tra questi 53 servizi posso disattivare per accelerare l’avvio di F18?
attualmente impiega circa 40 dalla schermata di GRUB a quella di LOGIN (LXDM)

(considerare che ho un desktop di 6 anni fa, una stampante EPSON, che all’avvio monto l’ hdd NTFS su cui è installato WIn, un router LAN, SELinux attivo, e…non so che altro aggiungere :-P)

lista ottenuta con il comando:

systemctl -t service

Con $ systemd-analyze blamepuoi avere un elenco dei servizi che vengono avviati all’accensione con il loro tempo di avvio, se lo posti qualcuno più esperto di me ti potrà dire se ci sono servizi che puoi disattivare.

ottimo programma, grazie.
