I just used the command:
yum remove autofs bluez-utils bluez-gnome bluez-libs cups iptables iptables-ipv6 irda-utils pcsc-lite pcsc-lite-libs spamassassin squid sendmail
and now my CentOS sticks at the loading screen. I am new to linux and am having trouble figuring out what my next step is. I have tried hitting 'i' when the system is booting for Interactive mode.
