Author: cperciva Date: Thu Nov 20 23:57:07 2014 New Revision: 372970 URL: https://svnweb.freebsd.org/changeset/ports/372970 QAT: https://qat.redports.org/buildarchive/r372970/ Log: Add firstboot-growfs port: When the system first boots, resize the (GPT) partition holding the root filesystem, then resize the (UFS) root filesystem. This is intended to be used in virtual machines where a VM image is built with one size but may be launched onto a larger disk. This will be used in EC2 images in the near future.
