No, this is a bug I found a couple of days ago. The fix is included in
the latest kernel in the CVS(but that has other problems now :( ). If
you apply the attached patch to the 0.1.0 source you will be ok. 

This bug affects "ash", so with an unpatched kernel you have to use
"sash" by editing the /etc/passwd file.

I was going to release some new precompiled kernels with the
patch(0.1.1) but this _unrunnability_ mess came up ... :(
