"The UNIX and Internet Fundamentals HOWTO" may also be useful. Get them all at http://www.tldp.org/docs.html#howto > You probably want to know about the init sequence, not the boot-up > sequence.

On RedHat, the initialisation script is actually /etc/rc.d/rc.sysinit, so you will have a line simillar to 'si::sysinit:/etc/rc.d/rc.sysinit' in your inittab file... > 2.

Redhat runs mingetty instead which is a minimal getty for consoles, so you might see a few lines like: "l:2345:respawn:/sbin/mingetty tty1" The last line in inittab reads "x:5:respawn:/etc/X11/prefdm -nodaemon", this is actually a shell script that runs xdm on tty7 in most cases > I'm not sure if there is a general turorial on the boot/init process, but > were I looking for one, I'd look through the HowTos at (for example) > www.linuxdoc.org . The HOWTOs recommended above should do the trick ;-) Sorry about the attention-to-detail (if I may say) on RedHat Ray, I'm just trying to make CR feel at home with his box ;-) --Arthur-- > -- > -------------------------------------------"Never tell me the odds!"-------- > Ray Olszewski -- Han Solo > Palo Alto, California, USA [EMAIL PROTECTED] > -------------------------------------------------------------------------- ----- > > - > To unsubscribe from this list: send the line "unsubscribe linux-newbie" in > the body of a message to [EMAIL PROTECTED] > More majordomo info at http://vger.kernel.org/majordomo-info.html > Please read the FAQ at http://www.linux-learn.org/faqs > - To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
