thanks for your confirmation!

By all means, please do! I'm also not particularly happy with this
temporary fix, but "it did get the job done"[TM] ;-)

No, i'd definitely prefer an "official" backported version of the
package, provided it's based on reasonably recent open-iscsi upstream
sources - there are several important fixes as of late not covered by
the current Jessie package sources. I particularly like your idea of
putting iscsiuio into its own package.
What's a real pain though, is the whole hassle with "_netdev", "LVM-
GROUPS", and still having to tweak the multipath init script. Well,
that's at least what i ended up with to get the order of things at
boot time at least almost right :-( Compared to the straightforward
use of targets through full iSOEs like e.g. the QME8262 cards, this
just feels awkward. Maybe it's just me doing something terribly wrong
;-)

Thanks & best regards,

    Frank
