Actually I found the following two article very close to what I want, minus
mkinitrd or raid autodetect partitions in the active disks

http://wiki.xtronics.com/index.php/Raid uses (uses mkinitrd)

or

I was looking for an article with that explains mkinitramfs and no
raid autodetect

Most likely, hence my email, hoping to escape that.

Thanks for your advise
