There may be some very sharp edges here while refactoring. - Move amd64/mk-vmimage.sh -> scripts/mk-vmimage.sh. - Remove vm-base target from Makefile.vm. - In vm-image target, use getopts flags for argument passing. - Create tools/vmimage.subr, containing default and prototype for the following functions that are used to drive the build, run in this order: vm_install_base() vm_extra_install_base() vm_extra_install_packages() vm_extra_install_ports() vm_extra_enable_services() vm_extra_pre_umount() vm_create_disk() vm_extra_create_disk() - In tools/azure.conf, override: vm_extra_install_base() vm_extra_pre_umount() vm_extra_create_disk() - In tools/openstack.conf, override: vm_extra_install_base() vm_extra_pre_umount() Sponsored by: The FreeBSD Foundation
