These symbolic links tell init that it needs to kill pppoe, innd, ntpd, httpd, mysqld, pvmd,
rarpd, bootparamd, nfs, rstatd, rusersd, rwalld, rwhod, squid, amd, mcserv, yp-
passwdd, dhcpd, smb, vncserver, arpwatch, named, snmpd, pxe, routed, mars-nwe,
ldap, kadmin, kprop, krb524, krb5kdc, gated, nscd, ypserv, ups, and irda. After all
processes are killed, init looks into the same directory and finds start scripts for kudzu, recon-
fig, ipchains, portmap, nfslock, autofs, random, netfs, apmd, identd, atd, pcm-
cia, sshd, rawdevices, xinetd, lpd, keytable, isdn, sendmail, gpm, canna, crond,
FreeWnn, xfs, anacron, and rhnsd, The last thing init does is run /etc/rc.d/rc.local
to run any special scripts configured for that host. At this point, the system is considered to be oper-
ating at runlevel 5.
After init has progressed through all of the runlevels, the /etc/inittab script forks a getty
process for each virtual console (login prompts) for each runlevel (runlevels 2-5 get all six; runlevel
1, which is single user mode, only gets one console; runlevels 0 and 6 get no virtual consoles). Basi-
cally, getty opens tty lines, sets their modes, prints the login prompt, gets the user's name, and then
