Few months ago, Karel Zak (from RedHat) forked util-linux which was unmaintained. The fork is called util-linux-ng and has an open development model (Mailing list, git repository). The list is really alive, with patches arriving everyday and commented quickly !
I had a simple patch on fdisk that I had sent to previous util-linux maintainer without getting an answer. I sent it to util-linux-ng two days ago, got an answer, posted an updated version yesterday, and it is now applied !
It looks like util-linux will now evolve after a few years sleeping, that's really good news :)
