A better description of what I want is "multiboot", instead of "dual
boot" in this thread. I can see having up to 4 systems installed, all
Debians, on one disk drive. There is an item in [1] which I see that reads:
6. Disable LVM support
If you look farther down your cite you'll find "What is LVM?". "Disabling LVM"
is only applicable to the OS/2 type of LVM. It causes the OS/2 kernel to use
native DOS-style FIFO assignment of drive letters.
which is puzzling. Can multiboot be set up within LVM on one disk drive?
Yes!
