I know this is a basic question but I've never really done it so I'm confused. How exactly do you install a second distribution on your machine? Say my current setup with centos is as follows:
100 mb for /dev/sda1 mounted at /boot
2000 mb for /dev/sda2 as swap
10000 mb for /dev/sda3 mounted at /
10000 mb of free space
When I install a second distribution, say ubuntu, I want to use the free space /dev/sda4 and mount it at root /. But where I mount /boot?
a) Do I somehow reuse the /dev/sda1 partition without reformatting it? (In which case, how do I get the initrd and vmlinuz and other files needed for ubuntu booting onto /dev/sda1?)
b) Or do I let /boot reside on /dev/sda4 with the rest of the file system? (In which case, I assume I manually make an entry for grub.conf in centos for ubuntu, using the appropriate root (hdX,Y)?)
c) something else? am I missing something basic?
