freebsd-update in official Vagrant boxes

[Oleksandr Tymoshenko]

Hello,

Official Vagrant boxes have freebsd-update running on first boot.
It takes several minutes to finish and if you have to destroy/create
VMs often it really slows things down.

What is the rationale behind enabling it and is there any way to disable
this behavior other than to build own box from modified src/ repo?

Thank you
