+I would like to wave in this direction.
+
+Enabling lvm by default would be a bit premature at the moment, but one
+thing we could add is the ability to choose this layout, like what
+debian does. You can choose to have lvm, but are not forced to.
+At the moment we provide 3 layouts:
+- simple
+- simple with /usr
+- server
+
+We could have other ones like:
+- /boot + lvm -> will hold /, swap, /home with extra space saved
+- /boot + lvm + encrypt
+
+At the moment there is one major blocker for lvm, if one check the
+encrypt checkbox, one gets screwed, see
+https://bugs.mageia.org/show_bug.cgi?id=188
+
+I’ve been using lvm here for quite a long time on mandriva, it works
+great but I still have to do manual things to get things right.
+
+Here are a few issues I encountered:
+- grub entry might be wrong you could end up with root=/dev in the
+  kernel line instead of /dev/vg/lv, bug not opened yet because I
+  haven’t been able to trigger the condition to encounter it.
+- initrd might be wrong if crypttab is empty (should open a bug for
+  this)
+- lvm might not be correctly detected and not included in initrd: I had
+  to export VG_LIST="vg" to get it work as expected
+
+And we have to test it thoroughly first !
+
