Apologies for this being off-topic in the strict sense, but this mailinglist probably has a relatively high proportion of people sharing my fate and having to manage o****e systems:
It is now 7 months that Robert has marked https://www.illumos.org/issues/3925 as fixed (THANK YOU, Robert!) but the issue still exists in current s11 (afaik their bug is 7143346) - and my old workaround does not work any more. I would like to share the result of two hours work to hopefully safe a similar amount for someone else.
