To mount the COWed file systems on the host using a LVM plugin Yes inside the UML it uses up ubd devices instead of loop devices currently only 8 are configurable, 16 possible with editing :( but once the ubd driver is cleaned up it should be possible to eventually have more ubd devices, my earlier patch was tested with 400 ubd devices mounted at once, but by that point the problems have already been solved. ________________________________________________________________ The best thing to hit the internet in years - Juno SpeedBand!
