The cloud9-image incremental build takes ~45 minutes with testlab and ~120 minutes with testlab + buildhistory. The base 45 minutes are ~10 minutes redoing the opkg indices (as reported earlier) and the rest is just mkfs.ext2 being stupid when it comes to using 4GB /dev/loopN files for images. regards, Koen _______________________________________________ Openembedded-core mailing list [email protected] http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-core
