     Hello everybody out there using minix –
-
+    
     I’m doing a (free) operating system (just a hobby, won’t be big and
     professional like gnu) for 386(486) AT clones. This has been brewing
     since april, and is starting to get ready. I’d like any feedback on
     things people like/dislike in minix, as my OS resembles it somewhat
     (same physical layout of the file-system (due to practical reasons)
     among other things).

     I’ve currently ported bash(1.08) and gcc(1.40), and things seem to work.
     This implies that I’ll get something practical within a few months, and
     I’d like to know what features most people would want. Any suggestions
     are welcome, but I won’t promise I’ll implement them 🙂

     PS. Yes – it’s free of any minix code, and it has a multi-threaded fs.
     It is NOT protable (uses 386 task switching etc), and it probably never
     will support anything other than AT-harddisks, as that’s all I have :-(.
