No need to re-create, --update=uuid should be enough according to the
man page.

Or you can just build a kernel with md built-in and use the kernel-level
RAID autodetection. In situations like this it is _much_ easier and
_much_ more robust than all the initrd-based solutions I have seen.
Also, if you install lilo to the RAID device instead of the MBR, and
install a bog-standard MBR using the install-mbr command on every drive,
your life will be easier.
