Has anyone tried the following:
(1) Create a disk image, which only has the contents of the /boot
(2) /etc/fstab should specify the root file system over NFS
(3) Boot the disk image in bhyve. The loader will parse /etc/fstab,
and it will also load the kernel and boot it. When the kernel
it will mount the root file system over NFS.
For a real system running with a BIOS, PXE can be used for a lot of this:
The pxeldr populates some kernel environment variables which are then
used to mount a root file system:
Has anyone tried manually specifying these variables
via the "bhyveload -e" arguments, and forcing the VM to mount its root file
system over NFS?
This would be handy for very quickly test booting a new buildworld.
