Yes.

Yes. You can put your root file system on a normal hard drive and use a
standard Linux distribution (e.g. Debian). For this to work you need to give
L4Linux direct access to the physical hard drive device.  This includes (maybe
not a complete list):

  - enable PCI-support in Linux
  - select the vPCI L4Linux driver
  - enable AHCI driver in Linux
  - put correct PCI-devices to L4Linux's vbus
