+Works fine in most of boxes, but I have a 'little' problem with others.
+They have IDE disks, and 3.1 kernel insists on driving them with IDE driver
+(pata_acpi) instead of SATA emulation (ata_piix). So those boxes
+which booted/mounted root via UUID survived and at least booted, using
+hda as root. But others where I had drives named by device /sed/sda1, did
+not even boot.
+
+For the moment I could try to change the boot to LABEL or UUID, but I think this
+is a bug, or at least a change wrt previous kernels.
+
+I don't know if it is a problem with in-kernel detection or with the generation
+of initrds, as new module-init-tools make initrd scripts complain about:
+
+direwolf:~# bootloader-config --action rebuild-initrds
+WARNING: "include /lib/module-init-tools/modprobe.compat" is deprecated, please use /etc/modprobe.d
+WARNING: Deprecated config file /etc/modprobe.conf, all config files belong into /etc/modprobe.d/.
+
+Some of this I think can be corrected:
+/lib/module-init-tools/modprobe.compat -> /etc/modprobe.d/compat.conf
+      (btw, is it still needed ? it was for migration from 2.4 to 2.6 and we are at 3.1 :-O )
+/etc/modules <==== I think it is unused !
+/etc/modprobe.preload -> deprectated for /etc/modprobe.preload.d
+/etc/modprobe.conf -> /etc/modprobe.d/modprobe.conf
+                      or split in /etc/modprobe.d/[scsi-host.conf, usb.conf, ....]
+
+But this late one generates other problem, /sbin/mkinitrd-mkinitrd references
+/etc/modprobe.conf everywhere. If it just changes location, it is just a change,
+but if it is split, ????
+
+werewolf:~# egrep mod.*conf /sbin/mkinitrd-mkinitrd
+modulefile=/etc/modules.conf   <============ ?????
+modulefile=/etc/modprobe.conf
+        modulefile=/etc/conf.modules
+            echo "options $module $options" >> $MNTIMAGE/etc/modprobe.conf
+        if [ "$module" = "zfcp" -a -f /etc/zfcp.conf ]; then
+
+And last, are modprobe binaries in initrd the same as in distro ? If the answer is yes,
+then probably the $MNTIMAGE/etc/modprobe.conf generated for initrd should also be relocated....
+
+In short, a little chaos. I don't know if it is affecting something actually.
+
+Hope this helps, at least as a detection of the problem.
