Well I am using the GCE machines for the exact same thing: I am building arm64
kernels and worlds, I am packaging with them (`make packages`) and I am also
making snapshots of them. I have a few months history, keeping old worlds and
images.

And yet, on the 30GB GCE machine, I have more than 10GB free space left:

[root at dev ~]# df -h
Filesystem         Size    Used   Avail Capacity  Mounted on
/dev/gpt/rootfs     28G     15G     11G    59%    /
devfs              1.0K    1.0K      0B   100%    /dev

[root at dev ~]# du -hs /usr/src/ /usr/obj
3.2G    /usr/src/
4.7G    /usr/obj

[root at dev ~]# gpart show da0
=>       3  62914549  da0  GPT  (30G)
         3        32    1  freebsd-boot  (16K)
        35   2097152    2  freebsd-swap  (1.0G)
   2097187  60817365    3  freebsd-ufs  (29G)

Granted, there are some big parts (like ZFS and bhyve) that I am not building:
[root at dev ~]# cat /etc/src.conf  
MALLOC_PRODUCTION=YES
WITH_CCACHE_BUILD=YES
WITHOUT_TESTS=YES
WITHOUT_BHYVE=YES
WITHOUT_PROFILE=YES
WITHOUT_ZFS=YES
WITHOUT_DEBUG_FILES=YES

I am not sure if it would fill up the 11GB of free space (I do take your word
on it) but yet your use case (build world and kernel in a bhyve machine)
doesn't seem compatible with mine (having Google Cloud machines running FreeBSD
for free, like it used to be before gcj committed the change).

I see three solutions:
1/ keep the root partition to a more reasonable size and make growfs and bhyve
work together (the cleanest solution)
2/ reduce temporarily the size by a few GB (maybe losing 2GB is enough, my
making VMSIZE=28GB) so that anybody can try and install the GCE images on
Google Cloud.  
3/ have special treatment for cloud images... most other Unix images are around
10GB, why is FreeBSD 32GB, like a Microsoft Windows image?

FreeBSD ? 32GB.

Glen, what do you think?
