How many OSes on one physical disk?

(Was: How to safely update open office to 2.0+?)

OK, I didn't pick up the point about an old version of Mandrake.
Now I understand the "safely" part. That does lead to a need
for some hacking.

If you want the latest apps, and don't want a major hacking
challenge each time you want to update, then it's best to have
a fairly fresh OS and application environment.

I've learned to move on to new distros every year or two, and
keep a few on the back burner so I know what's out there.
Otherwise, Linux definitely has forced-obsolescence problems
like any other environment, because the software and
hardware continue to develop.

Since I also do some work in Windows, and share files
between Windows and Linux, I have my data neatly tucked
into separate partitions, mostly FAT32, and this means I can
replace an operating system easily without having to rebuild
my whole life.

AS A RESULT, I'd like to have lots of Linux versions in place
at the same time, for multi-booting. This leads to a partitioning
question.

I have this nice 130-GB disk. I would like to break it up into a
whole slew of partitions, but I gather there are definite limits.
Thus I can't have, for example, 99 different OSes on this drive
each with its own boot partition. Right?

How far can I go in this direction? Is there a practical way to
have partitions within partitions or something? Something like
an ISO filesystem housed in an ordinary file? If so can it
update its data while running? Etc. . . .

I'm thinking that VMWare and lots of virtual profiles could be
one way to go, and that way I could keep one basic system
running all the time while I'm tinkering with the others. But I'd
like to look into the multi-multi-boot approach too, if I could put
lots of boot partitions on one disk.

Ideas?

Thanks,

Vic

What you don't understand is that he is running an outdated and
unsupported version of Mandrake, so there aren't any pre-made
packages for his distribution containing the latest version of OO.
