All,
Would it help to create a script like the attached (I'd
call it install-port-conf or install-conf)? What this would
do (should you remove the echo from the cp lines...) is
check for the currently installed package from ${PKGORIGIN}
and check to see if the file to be installed has been modified
from the original distributed file. If the user has modified
it, then we'll leave it alone and create the new file as
${FILE}.new. If the user hasn't modified it, copy the old
file to ${FILE}.old and install the new ${FILE}
From the makefile it might be used as follows:
INSTALL_CONF=/path/to/install-conf # probably shipped in port files
# ...
do-install:
${INSTALL_CONF} ${PKGORIGIN} ${WRKDIR}/server.xml ${APP_HOME}/conf/server.xml
${INSTALL_CONF} ${PKGORIGIN} ${WRKSRC}/web.xml ${APP_HOME}/conf/web.xml
Of course, the attached script would need to be completed. The only
thing it does reliably is tell you if a previously installed version
of a file to be installed was modified by the user.
Comments?
