BTW. with regard to the console.log file I really don't think it

generation of the file entirely inside the jail since it's just not
worth the risk/complexity. I think it should be possible to do this
with jail(8) in -CURRENT (see -J flag), but:

When -J operates on a file inside a jail, it create the same security
hole as the one from security advisory, because it opens a file before
calling jail(2).
I fully agree that console.log should be outside a jail. At least noone
proposed safe solution so far, which also means it's not an easy fix.
