This requires two sets of changes. Firstly, for non-FreeBSD, we do not know where tools are in PATH (and it is likely that some are not in system directories and have been built as bootstrap tools during the build), so we should leave PATH alone and trust the user. Secondly, makefs needs a master.passwd for building images from a METALOG file, so pass the directory in the image tree to makefs's -N option in order to pick up a valid FreeBSD master.passwd; this is unnecessary on FreeBSD (except in the edge case of building an image that refers to users or groups not present in the host's database, which is unlikely but technically possible) but harmless so can be done unconditionally.
