+ * ls -l now displays lnik names outside the current directory,
+ Patch thanks to Eric Delaunay
+ * init now properly handles sparc serial consoles and does a
+ better job of finding the real consol device rather than using
+ /dev/console which doesn't support job control. Patch also
+ thanks to Eric Delaunay.

0.33
* Fixed a bug where init could hang instead of rebooting.
* Removed some debugging noise from init.c
