systemd: root device on iscsi

[Jeremy Sanders]

Hi - is an iscsi root device a supported configuration setup with F16 and 
systemd? I asked on #systemd, and got pointed here.

We're using dracut to boot diskless systems with root devices on iscsi. This 
works fine for booting using Fedora 16 and systemd.

Unfortunately, on shutdown the system hangs. It stops the network interface 
before mounting the root device read-only or stopping the iscsi service 
(leaving the fedora iscsi target in a confused state too). On Fedora 14, 
this worked fine with the old fashioned init system.

In the old init system you used to be able to put a "_netdev" flag in fstab, 
which would fix this problem. This doesn't seem to work now.

Is this a simple bug or a bigger issue?

I could imagine we could write some sort of evil systemd service which would 
run busybox (perhaps copied to tmpfs) to kill processes, remount root, kill 
off iscsi and run halt or reboot depending on the run level, before the 
network was stopped. That would be an awful hack (if it even worked).
