It's not that simple if /usr is on LVM, / is not large enough to hold /usr and resizing the partition is really tricky. In that case, the simplest option is to start using an initramfs. Once that is working, you can get rid of the separate root partition and move that filesystem into the VG too. -- Neil Bothwick WinErr 004: Erroneous error - Nothing is wrong
