Having trouble with firstboot-growfs

[Andrew Villano]

 I've used Firstboot-growfs a few times and it usually goes without a snag.
I touch /firstboot, reboot the box and when it comes back up it resizes the
partition and resizes the filesystem.

I've just spun up a FreeBSD 12 box,
[vagrant at freebsd ~]$ freebsd-version
12.0-RELEASE-p5

I was able to resize the VMDK (by converting it to a VDI.. etc)

3. Name: ada0p3
   Mediasize: 32212254720 (30G)

   type: freebsd-ufs
   index: 3
   end: 65011837
   start: 2097278
Consumers:
1. Name: ada0
   Mediasize: 157286400000 (146G)
   Sectorsize: 512
   Mode: r2w2e5

but I can't seem to get past this point. Nothing shows up in
/var/log/messages or in dmesg to indicate that there was a failure.
Strangely enough on reboot, the triggerfile /firstboot is gone as if to
indicate something was done.


Thanks.
