it 'should' recover from network disconects, like pulling out cable, or
rebooting the target, but I think that this will only work if there is no
major activity - I better test this one again.
it should also flush buffers when you shut down the host, this was a major
pain with the old versions.

ok, fixed the 'typos', I also forgot the sample rc.d/iscsi,

------
problems with the above script:
- no background fsck
- restart will mess the exports file
- the wait loop should be replaced by something more deterministic.

Ok, but can't say I look forward to hear from you :-)
