aha... now i understand :)

what you really need is some sort of weak dependency which implies that
if the package is already installed then it must be a specific rev.

ok cool...

well according to the mdadm changelog the -Ac partitions bug was fixed
in 1.10.0 ... so we'd want to stick something like this into
Templates.cfg

!case "`mdadm --version 2>&1`" in
!        mdadm\ -\ v1.[1-9][^0-9]*)
!                mdadm --assemble <TMPL_VAR NAME=target> --uuid <TMPL_VAR NAME=uuid> \
!                        <TMPL_LOOP NAME=components> <TMPL_VAR NAME=dev></TMPL_LOOP>
!                ;;
!        *)
!                mdadm -Ac partitions <TMPL_VAR NAME=target> --uuid <TMPL_VAR NAME=uuid>
!                ;;
!esac

hmm well i need to handle mdadm v0.x too i guess... i'm trying to avoid 
added grep to the initrd.

let me know if the above is generally what you're looking for -- an 
alternative is to test the mdadm version at mkinitrd time but i didn't see 
a way to do that without mucking in the perl (which i don't mind doing 
either).

i probably won't be able to test a patch for a week or two though.

thanks
