When qemu suffers a segmentation fault, monitor code might still

This patch creates a dummy /etc/passwd on guest creation.
This is done because some applications (read: git) get angry when they

when trying to create a VM using a RAW image on a zfs filesystem, i get an

has anyone made this work? is it a known issue and/or is there a workaround?
more detail:
- i can create the VM on a ext4 filesystem
- i can create the VM on a ZFS zvol ("raw" devi
