The difference between the two being that the init.d scripts are run once,
whereas the /etc/inittab entries can be set to keep the program running on
the tty.
For /etc/inittab, I use the -n and -l switches to getty, like this:
#put a top on VT 11
#note: this runs as root, with kill priviledges and everything
11:23:respawn:nice /sbin/getty -n -l /usr/bin/top 38400 tty11
#show /var/log/syslog on VT 12
#note: /etc/cron.daily/syslogd kills whatever's using /dev/tty12
12:23:respawn:/sbin/getty -n -l /usr/local/bin/showlog 38400 tty12
I consider my console to be secure; if you don't, you probably want to give
top the secure switch (top s) - you'll need to put that in a shell script,
though, because getty doesn't let you pass parameters. The showlog script
is: date +"$0 started %c"; /usr/bin/tail -f /var/log/syslog
