I set up a machine that booted 4 different Centos installations the other day. All you have to do is tell the installer that you want to do a custom partitioning scheme, then point it to /dev/sda or /dev/sdb or whatever, and tell it to use X amount of the space on that drive. Don't install the boot loader on anything but the first install, then add the new partitions/setups manually to grub.conf as you create them. I found it easiest to not use a /boot partition though there is probably a way to do it with one as well. Here is the grub.conf that I ended up with on my 4-way booting machine: # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You do not have a /boot partition. This means that # all kernel and initrd paths are relative to /, eg. # root (hd0,0) # kernel /boot/vmlinuz-version ro root=/dev/sda1 # initrd /boot/initrd-version.img #boot=/dev/sda default=0 timeout=5 splashimage=(hd0,0)/boot/grub/splash.xpm.gz hiddenmenu title HomeComputer (2.6.18-53.1.4.el5PAE) root (hd0,0) kernel /boot/vmlinuz-2.6.18-53.1.4.el5PAE ro root=LABEL=/ rhgb quiet initrd /boot/initrd-2.6.18-53.1.4.el5PAE.img title AnsweringMachine root (hd0,3) kernel /boot/vmlinuz-2.6.18-53.1.4.el5PAE ro root=/dev/sda4 rhgb quiet initrd /boot/initrd-2.6.18-53.1.4.el5PAE.img title ApplicationServer root (hd1,0) kernel /boot/vmlinuz-2.6.18-53.1.4.el5PAE ro root=/dev/sdb1 rhgb quiet initrd /boot/initrd-2.6.18-53.1.4.el5PAE.img title WebServer root (hd1,1) kernel /boot/vmlinuz-2.6.18-53.1.4.el5PAE ro root=/dev/sdb2 rhgb quiet initrd /boot/initrd-2.6.18-53.1.4.el5PAE.img -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com
