Grub works with 2 stages: 1º - MBR ( Master Boot Record ) , with instruction to access the partition where store kernel , initrd and grub.conf 2º - Reads the partition indicated on 1º stage (MBR), to read grub.conf with all instruction to boot the OS. Now the question why we cannot use /boot on LVM. LVM is a Logical Volume Manager, GRUB no have support yet to read LVM. You'll see this LVM structure after the kernel boot and load the LVM modules. You could see what filesystems are support by Grub access your /boot after installation, looking into /boot/grub. Only Grub version 2 could access partitions /boot with LVM. ( I find this information now ) - You'll not have problem using SWAP on LVM, but we need think about all situations. If you running some software that use too much SWAP area, recommend you put your SWAP on the firsts primary partition on your disk, because there are area more fast I/O. If you want know more about that looking for about ZCAV. (This is applicable to electrical mechanical disk, no Solid State Disks,SSD). Let's think you need more SWAP space, but your using SWAP on LVM, you could create a new LVM and add to SWAP area. swapon -s (you could see information how many swap partition or files you have and how much is the use of them) best regards, --aslan
