good one ! , yeah maybe the typical LVM lunacy, that's why I tell others to always choose Standard Partitioning hehe.
The only lunacy here is your assumption that all other people are also not capable of understanding what you can't and are afraid of. Some of the people you "tell others to always choose Standard Partitioning hehe." are perhaps capable of understanding lvm and its benefits and aren't fearful like you.
If you had actually read and understood the linked page you would know that it doesn't really have anything to do with lvm. Although it mentions lvm at the beginning the example it gives is how to boot a kernel and initrd with root on a regular partition.
grub> linux (hd0,1)/vmlinuz-3.0.0-1.fc16.i686 root=/dev/sda3 rhgb quiet selinux=0
