[arch-general] Better NILFS2 Support

I just spent some time setting up my new laptop with an SSD to use NILFS2 as its root filesystem and I'm very pleased with the performance. In an effort to get better support for NILFS2 in arch I've added a request to move nilfs-utils to the base group and submitted a patch to initscripts to bring up the nlfs_cleanerd daemon if root is formatted as NILFS2. If NILFS2 is used on other partitions the mount command brings up the daemon on it's own. These two bugs should make it easier to add NILFS2 support to the Arch Installation Framework. Related bugs here, patch comments welcome: http://bugs.archlinux.org/task/20260 http://bugs.archlinux.org/task/20261 Cheers, alexmat
