Fedora switched from Grub Legacy to Grub 2 in Fedora 16. There should be nothing holding back a fresh install from not having /boot on the same logical volume as /.<div><br></div><div><br></div><div>As to the why..</div><div>
Grub Legacy relied on loading a file system, /boot, to continue chain loading an OS and it only had support for a few file systems built in. Grub 2 gets around this by loading the first block of a stage 1.5 image directly from a block address on disk. That image then has the drivers to load LVM, MD RAID, etc. and continue up the chain.<br>

</div></div>You don't mention what distro you're running, but there's an article<br>
with some promising information to be found at<br>
<a href="http://jim.studt.net/depository/index.php/debian-lenny-and-grub-with-boot-in-lvm" target="_blank">http://jim.studt.net/depository/index.php/debian-lenny-and-grub-with-boot-in-lvm</a><br>
<br>
I can't say if there are any distro installers that support it at this<br>
point. I don't recall it being an option with Fedora 15, and it's<br>
definitely not something the Debian 6.0 installer can handle.<br>
<br>
[I had a big bunch of text in here describing my setup, but it's not<br>
really relevant (/boot is in an MD RAID1 mirror, not on a logical<br>
volume, and there are _no_ type 8e "partitions" (GPT, baby!).]<br>
<br>
Let us know how it goes.<br>
