No problem :-)

Sure it's help.

Interesting, may be I will reconsider switching…

I read it, but there's no words about VNET and vanilla jails. Seems a little
bit more difficult and all the jails must be switch at the same time (as I saw
from my small experience).

But I read to that you are not very happy with VNET jails :-)

Btw, it's very hard to make my own opion with all the different experiences I
read. :-)

That said, and off topic, thanks for your blog, your shared experiences,
FreshPorts and all you do for the community.
