commit 5050b464aeda1d775a5f36d000daa7473a214977
Author:     Colin Percival <cperciva@FreeBSD.org>

    release: Pass PKG_INSTALL_EPOCH to vmimage.subr
    
    This value, if not already set, comes from the timestamp of the most
    recent git commit (which is now also available in src/release code as
    GITEPOCH) or 0 if git is not installed.
    
    This should allow /var/db/pkg/local.sqlite to be reproducible in VM
    images which have packages installed (e.g. cloudware).
