[bug#30629] [PATCH 0/5] Detect missing modules in the initrd

[Danny Milosavljevic]

Hi Ludo,

I've cloned master and checked it again, everything is fine except for the test 
failures :->

It's not so bad, don't worry.

I think it's right in that:

/mnt/etc/config.scm:1:300: error: you need these modules in the initrd for 
/dev/vdb2: virtio_blk virtio_pci

That means the system tests now have to be a little bit aware that they are 
running in a VM...

Same for separate-home-os and installed-os and maybe others - they are still 
running.
