Reading this thread & all of the archive that was abel to browse (with 
all of the right packages installed from Arjan's APT server), I am still 
not able to figure out what is the migration patch from FC1+LVM1 to 
FC2+LVM2.

I am still wondering how to make a 2.6 kernel (Arjan's -149) recognize 
my LVM1 using dm loaded in an initrd. From a mail archive, I have seen 
how to make|force an initrd using lvm2 from a 2.4 running kernel 
(hacking mkinitrd script), but this is not what I want: I am not even 
speaking of migrating to LVM2 there. Anyone that can help mee booting 
2.6 with LVM1 inittrd[1]?

Or shall I first migrate to LVM2 under 2.4 & then to 2.6? In this case, 
do I have to make my own hand-made kernel with DM patches or is the 
current DM support in 2.4.22-66 enough? I assume that the 
above-mentionned vgconvert stage is the tricky no-way-back point, right?

So far, I have migrated to FC2-pre (tupdates on freshrpms) all of my 
systems without any big issue (but the USB keyboard & mouse... case to 
add an alias in modprobe|modules.conf  by default?) but my LVM boxes are 
stuck in 2.4.

TIA

[1] Default mkinitrd fails, otherwise I would not ask. Eh?

% rpm -q mkinitrd device-mapper lvm lvm2
mkinitrd-3.5.15.1-2
device-mapper-1.00.07-1
lvm-1.0.3-17
lvm2-2.00.08-2
