Sean, Does poudriere work with previously-established roots or does it have to generate its own? I'm using crochet <https://github.com/kientzle/crochet-freebsd>; to create my image, so I can do whatever I want to the filesystem it creates and have it apply to the image. Also, will poudriere actually install a package and modify necessary files to let the system know a port is installed, or does it only create the package and leave it to me to install? -Jeremy On Wed, Dec 24, 2014 at 8:16 PM, Sean Bruno <sbruno@ignoranthack.me> wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA512 > > On 12/24/14 16:34, Jeremy Brown wrote: > > I have a VM running FreeBSD 10.1 x64 that I'm trying to use to > > create an image that will run on a Raspberry Pi.
