why on earth do you want to set ALT_RUN=/dev/md ?
it is messy enough as it is, let's keep assuming /dev/md contains only
array device files.

besides that you will discover that the only way to make mdmon work is 
setting VAR_RUN and ALT_RUN to the same value, something we can
guarantee to be writable even in the direst situation, and i'd keep
/dev/.mdadm

this "hunt the mapfile" thing is already ugly as it is, why do we need
an ALT_MAPNAME? if there was any value (except for allowing to set
ALT_RUN to /dev/md) to having the mapfile named differently, just force
it to be called mdadm.map everywere (or incremental.map so the name
reflects the need for the file existance)
