[uml-user] cannot use "hostfs" or "humfs"

[Han <kee...@gm...>]

Hi,

I am using linux-2.6.24 UML in 32-bit x86.  I booted up UML
successfully but was not able to mount using hostfs or humfs.

root@(none):~# mount none /host -t hostfs
mount: unknown filesystem type 'hostfs'

root@(none):~# mount none /mnt-home/ -t humfs -o /home
mount: unknown filesystem type 'humfs'

The rootfs I used to boot up UML is:  Debian-Squeeze-x86-root_fs.

Any ideas why hostfs and humfs are "unknown"?

thanks
Han
