The way I do it is using the init scripts provided by my distro (Mandriva, in 
this case) to start drbd and then start heartbeat.

I don't see a particular benefit to starting said software from /etc/inittab 
for a couple of reasons:

1) The drbd init script only needs to run once (as far as I can see) on each 
node; if your system can't run a script reliably at boot then you have bigger 
things to worry about.

2) If heartbeat crashes, I'd rather know about it so I can analyse why it 
crashed, rather than it be respawned automatically by init and potentially 
cause more damage.
