Way too much.

Can be on a logical volume, too.

Why? Use the LiveCD.

Can also be on a logical volume, but needs an initrd/initramfs. 4G is too
large, IMHO. Mine is 256M.

I've even placed _all_ of my machines on logical volumes (using EVMS), and
it also works well.

Partition table:
# fdisk -l /dev/hda
Disk /dev/hda: 10.0 GB, 10005037056 bytes
240 heads, 63 sectors/track, 1292 cylinders
Units = cylinders of 15120 * 512 = 7741440 bytes

/dev/hda1 * 1 8 60448+ 83 Linux
/dev/hda2 9 1292 9707040 83 Linux
Everything below resides on hda2.

Note that this machine gets $HOME from NFS, so I don't list it here. I would
usually create a separate volume for each users home dir, so that I don't
have to care about quota (if needed).
grub.conf:
title Gentoo Linux 2.6
kernel /vmlinuz-2.6.12.3 root=/dev/ram0 realroot=/dev/evms/root
vga=794
initrd=/initrd-2.6.12.3.gz
Note that I use a self-made initrd, which activates the EVMS volumes (needed
because / is an EVMS volume, too), does a pivot_root from root to realroot
and then starts up the real thing.
