Well
Are you gonna put all that in 1 or how many partitions?
2?
I put all this in my Ultimate edition (ubuntu-9.04)
partition
http://multidistro.com/fluxboxp/multidistro.png
thats
GRML-magix
KNOPPIX
and pmagic-4.5
all persistent too
http://multidistro.com/fluxboxp/m2.png
thats my other 9.04 partition
which has
browserlinux puppy
lighthousepuppy
paw-rc puppy
and pmagic-4.4
and oh wattOS beta running a casper-rw persistent
so, the point being you can easily add live distro's to the partition without affecting the
ubuntu or slack installation there
