what are the restrictions on bootable partitions?

[Robert P. J. Day]

  what are the restrictions on where i can install another linux distro
onto my fedora core (actually, FC2-t3) system so that grub can find it?
(even though this is a test version of fedora, this question actually
refers to FC distros in general.)

  typically, for historical reasons, even when i use LVM, i create a small
primary, ext3 filesystem for /boot, and use LVM for the rest of the drive.
is there any compelling reason for doing this anymore?  what's the 
recommended strategy for LVM?  and need for a non-LVM filesystem on newer
machines?

  and, on top of all this, i want to add at least one other distro to the
system; in this case, xandros 2.0, for evaluation for a client.  can i add
this additional distro entirely within LVM and have grub still find it
properly?  i suspect yes, but i wanted to make sure before i spent all 
that installing.  thanks.
