Hi Fotis, Since I'm not used to unikernels, I'm a little confused by this; I'd appreciate some explanation. In your unikernel, does the root filesystem just contain data? I mean being a 'unikernel' aren't all the binaries and support all linked into the kernel itself? Dave -- Dr. David Alan Gilbert / dgilb...@redhat.com / Manchester, UK
