Make Qomo, Ubuntu, and Fedora Live together in harmony in the same partition of the hard disk

Let Qomo, Ubuntu, and Fedora Live together in harmony together in the same partition of the hard disk-Linux general technology-Linux technology and application information. The following is a detailed description. In the past, when you wanted to enable a Live system from the hard disk, we usually emptied a partition. Recently, through repeated experiments, Qomo, Ubuntu, and Fedora have always lived together in the same partition of the hard disk. The boot file is as follows:
# Chenggong on/dev/sda12
Title Fedora LiveCD YingKpan Anzhuang
Root (hd0, 11)
Kernel (hd0, 11)/isolinux/vmlinuz0 root = live:/dev/sda12 livedisk_iso =/Fedora-14-Beta-x86_64-Live.iso liveimg quiet rhgb rootfstype = auto vga = 791
Initrd (hd0, 11)/isolinux/initrd0.img
Boot

# Chenggong on/dev/sda12
Title Ubuntu YingK/pan Anzhuang
Root (hd0, 11)/Ubuntu
Kernel (hd0, 11)/Ubuntu/vmlinuz boot = casper iso-scan/filename =/Ubuntu/ubuntu-10.04.1-desktop-amd64.iso ro quiet splash locale = zh_CN.UTF-8
Initrd (hd0, 11)/Ubuntu/initrd. lz

# Chenggong on/dev/sda12
Title Qomo1.0 YingK/pan Anzhuang
Root (hd0, 11)/Qomo
Kernel (hd0, 11)/Qomo/isolinux/vmlinuz0 ro root = livedisk: /dev/sda12 livedisk_iso =/Qomo/Qomo-1.0.0-i686-Live.iso liveimg nodmraid rhgb vga = 788 rdblacklist = b44 rdblacklist = b43 rdblacklist = ssb
Initrd (hd0, 11)/Qomo/isolinux/initrd0.img
Boot
Note: The Fedora image can only be placed in the root directory, and the absolute path under the root directory may be used for running. Both Qomo and Ubuntu images can be located in the lower-level directory of the root directory, possible allowed relative paths for running.
For laruence, looking at the boot menu, the corresponding files will be extracted and placed in the corresponding directory, and the image files will be located. Don't shake.
Here, I wish the old birds a better experience in multiple Linux Live systems.
