Well, this is just an interim fix, for Jessie. For sid and later, we'll
also ship the systemd files that'll be independent.

That's something which'll require co-ordination with systemd team, and
some testing once we have that support.

I don't have all the history, but I believe you could have your root fs
being served off of an NFS root file system, while providing data LUNs
over iSCSI.

Again, I don't recollect every detail. But the open-iscsi script deals
with the userspace daemon. Where as the umountiscsi.sh script is only
used to deal with the iSCSI block devices mount/umount. It also takes
care of LVM devices, if any, created on top of it.

The iscsid daemon is not needed for the full operation of the iSCSI
service. Hence the daemon handling is separated from the iSCSI sessions
that are handled in-kernel.
