Code review comment for ~redriver/cloud-init:frbsd-azure-branch

Hi,

I have been doing some testing on FreeBSD.

The current growpart seems to work fine with FreeBSD 11.0 with GPT/UFS - the partition gets resized. The issue is with filesystem resize in resizefs. Its a simple fix, before you can modify the MBR you must first set kern.geom.debugflags=16, then when calling growfs you must pass the '-y' flag. You should then set debugflags back to it's original value.

Basically this, I did a quick hack to test and seems ok:

current_debugflags = sysctl -n kern.geom.debugflags
sysctl kern.geom.debugflags=16
growfs -y /dev/vtbd0p2
sysctl kern.geom.debugflags=current_debugflags
