Hi everyone,

I'm creating some internal-only ports and I'm trying to maintain the
permissions and owners of the files present in the distfile.tar.gz when
they get packaged up for install.

When I "make extract", the "do-extract" target is performing a chmod and
chown on everything, as seen from the following excerpt from the
bsd.port.mk file:


.if !target(do-extract)
do-extract: ${EXTRACT_WRKDIR}
        @for file in ${EXTRACT_ONLY}; do \
                if ! (cd ${EXTRACT_WRKDIR} && ${EXTRACT_CMD}
${EXTRACT_BEFORE_ARGS} ${_DISTDIR}/$$file ${EXTRACT_AFTER_ARGS});\
                then \
                        exit 1; \
                fi; \
        done
        @if [ ${UID} = 0 ]; then \
                ${CHMOD} -R ug-s ${WRKDIR}; \
                ${CHOWN} -R 0:0 ${WRKDIR}; \
        fi
.endif


Short of commenting those lines out (which I really don't want to do
because I have 0 idea why it's there or what I'd break with other ports)
is there any way at all to maintain the ownership of the files? 


Thanks,

Joseph Ward
