I said that because I have several roms on my hd2 test and some are GB others are ICS or JB.True, we use portadroid 4.0 and the folder (and the rel-path in startup.txt) is called ics. It is just one less thing to do when porting to leave it as is. I assume that ppl will change the name of the new build when installing anyway, so as to have a number of builds on sdcard. I have tried renaming the build folder before but it gets confusing when giving path names ie "put meta-inf into sdcard/whatever-you-have called-your-build-folder/root". Good point though.
