Author: cperciva Date: Fri Feb 8 19:19:31 2019 New Revision: 343918 URL: https://svnweb.freebsd.org/changeset/base/343918 Log: Teach /etc/rc.d/growfs how to handle systems running ZFS. There are many cases which this code does not handle (e.g. ZFS mirrors) but the code can handle the single-disk case -- so it's enough to take care of the "disk image which gets booted into a VM with a larger than expected disk" case for which this firstboot script was created.
