As evidence only two lines of jail.sh reference SRCPATH
other than where -S assigns to it:

# grep "SRCPATH" /usr/local/share/poudriere/jail.sh
	[ -z "${SRCPATH}" ] && DISTS="${DISTS} src"
	[ -n "$SRCPATH" ] && jset ${JAILNAME} srcpath ${SRCPATH}
			SRCPATH=${OPTARG}

Also, every non-comment instance of /usr/src in jail.sh
is preceded by just ${JAILMNT} or ${SRC_BASE} or by
nothing:

# grep "\/usr\/src" /usr/local/share/poudriere/jail.sh | more
        SRC_BASE="${JAILMNT}/usr/src"
        export SRC_BASE=${JAILMNT}/usr/src
        # Otherwise it's the older broken one, so use the host /usr/src
                : ${XDEV_SRC:=/usr/src}
        msg_n "Copying ${SRC_BASE} to ${JAILMNT}/usr/src..."
        mkdir -p ${JAILMNT}/usr/src
        if [ -f ${SRC_BASE}/usr/src/.cpignore ]; then
        cpdup -i0 ${cpignore_flag} ${SRC_BASE} ${JAILMNT}/usr/src
        SRC_BASE="${JAILMNT}/usr/src"


It leaves me wondering if some notation like:

${SRCPATH:-${JAILMNT}}/usr/src

should be in use in some places where

${JAILMNT}/usr/src

is now in use. I'm no so sure that the
analogous is appropriate for the one
example of :

${SRC_BASE}/usr/src
