My feature request right now are this:
1) Add native ext4 support. I'm missing your backup service because you don't support ext4 which I'm using and which is better than old ext3 in almost every aspect.
2) Add write barrier support. It will definitely help with data integrity for people, who run unstable systems or use Freemont data center with built-in reboots
3) Update your recovery distro because it is really very, very outdated. Because of this, I'm using 2gb portion of precious hdd space to house another deployment which I will be able to use in case of emergency to diagnose/repair my production deployment.
