[uml-devel] tmpfs broken?

["Sven Köhler" <skoehler@upb.de>]

Hi,

when booting my 2.6.1-um1 kernel, it says "Could not kern_mount tmpfs" 
and afterwards - when the system has booted - i really cannot mount a 
tmpfs. I'm in doubt if i need it, but my gentoo likes to mount a tmpfs 
to /dev/shm. Is tmpfs supposed to work?

Thx
   Sven
