I have e2fs partition on my /dev/sda1 USB memory stick device mounted as /mnt/vl-hot/sda/vol1. I want to install VL Live there. So I run vliveinstall and I see only "placeholder". There are some instructions, that the target partition where the VL Live should be installed should be formated and mounted. As you see, I've done this, so what's the problem with vliveinstall?
