make release-sets - question

[Jiri B]

Hello,

I try to understand why 'release-sets' does copy kernel.tgz from DESTDIR
into OS /usr? Could anybody explain the logic behind?

Thank you.

build1$ sed -n '/^release-sets:$/,/^$/p' /usr/src/etc/Makefile      
release-sets:
        su ${BUILDUSER} -c 'exec ${MAKE} distribution'
        su ${BUILDUSER} -c 'exec ${MAKE} kernels'
        cp -p ${DESTDIR}/usr/share/relink/kernel.tgz 
/usr/share/relink/kernel.tgz
        ${MAKE} bootblocks
        cd ${RELEASEDIR} && rm -f SHA256
        cd ../distrib/sets && exec su ${BUILDUSER} -c 'exec sh maketars 
${OSrev}'

Jiri
