Thanks for the reply
I've got it working with a root_fs image, but I would like to use to
hostfs, when I attempt to use it with the command line
hostfs as root is not well supported.
good to know, I'll avoid useing it for now. is it on the roadmap to be
supported?
./linux ssl=xterm console=xterm root=/dev/root
rootflags=/sandboxes/amd64uml/ rootfstype=hostfs
I get an error about a missing /dev/shm/root
/dev/shm/root? It would be very strange, never seen that.
useing this command line (running as root)
./linux ssl=xterm console=xterm root=/dev/root rootflags=/sandboxes/amd64uml/
rootfstype=hostfs
here is the tail end of the errors I get. what other testing would you
like me to do (or since it's not well supported should I just drop it?)

fsck.ext2: No such device or address while trying to open /dev/shm/root
Possibly non-existent or swap device?
fsck failed. Please repair manually and reboot. Please note
that the root file system is currently mounted read-only. To
remount it read-write:
# mount -n -o remount,rw /
CONTROL-D will exit from this shell and REBOOT the system.
the other big question that I have is about the networking.
as I attempt to use the tuntap interface to configure the uml eth0 as per
the howto I am creating the tap0 device, but when the uml system boots it
doesn't show any ethn interfaces and on the console I get the following
error.
Have you added eth0=tuntap,tap0 to the cmd line of UML according to:
http://user-mode-linux.sourceforge.net/networking.html
(See section "TUN/TAP with a preconfigured tap device")
useing this command line
./amd64uml/linux ssl=xterm console=xterm eth0=tuntap,tap0 eth1=tuntap,tap1
with ifconfig reporting
