+Indeed it did reboot without too much problem here with lvm for / & /home.
+However i noticed that the initrd is bigger than the old mkinitrd :
+-rw-r--r--  1 root root 7,8M oct.  20 22:40 initrd-3.1.0-
+desktop-0.rc10.1.mga2.img
+-rw-------  1 root root 5,4M oct.  18 09:50 initrd-3.1.0-
+desktop-0.rc10.1.mga2.img-old
+
+During the creation of the initrd there's several warnings  about moving 
+several files to /etc/modprobe.d/ (such as the 
+/etc/modprobe.conf), i noticed especially this one 
+
+« perl: "include /lib/module-init-tools/modprobe.compat" is deprecated, please 
+use /etc/modprobe.d 
+»
+It seems this file was created to ensure transition between the 2.4 & 2.6 
+kernel release, maybe we can safely drop it now ?
+
