i concur with this.
Marcello: try to migrate from a root-on-LVM1/2.4 to LVM2/2.6; it is very
painful. major/minor # changes, more stuff required in initrd, "dm"
doesn't appear in 2.6's /proc/partitions . . .

it is a painful upgrade - probably partly due to lack of
tools/documentation on DMs part, but also equally because 2.4->2.6 is a bug
jump in a kernel and its exacerbated by LVM1->LVM2 changes...


cheers,

lincoln.
