Great!

I think that what you have suggested is the best way to do it.

Does it have to be a module? A simple 'iscsi-init' tool that runs from
userspace should be able to do what the iscsi-init module does. Before I
found out that iscsi-init existed, I thought of creating a very cut down
iscsid that just set up the connection and then died. With such a tool +
ifconfig I'd be able to do what I'm doing now, although if I wanted to
do dhcp it would be a bit more complicated. The nice thing about
iscsi-init is that it's all rolled into one but that sounds like what
Manish was objecting to. It would also be a bit harder to get it into
initrd automatically but I already need to create the device node via
script.

I put 'down /bin/false' in the interface definition in /etc/networks and
it stops the interface being shutdown on system shutdown, but as you say
this doesn't help when the iscsi init script shuts down all the
connections.
