Well, there is also a technical reason. istgt requires a restart of the
target/session every time a LUN is deleted or updated this breaks
client side attachments. iet requires a reload of the target every time
a LUN is deleted or updated which might reorder LUN numbers and hereby
break client side attachments for the LXC feature.

targetcli seems very promissing providing feature nearby or on par with
comstar. Also LUN's can be added, deleted, and updated inside the same
session without changing anything to unchanged LUN's. I need more
testing to verify this for certain but if I am able to verify this I
will consider targetcli as target for enterprise ready. This will mean
that Proxmox will contain two enterprise graded zfs-over-iscsi
implementations on two different platforms (Linux and Solaris).

Maybe worth adding on the todo list for Proxmox?
