Got it, built it already.  And found a missing file, which when found in an 
older tree, is 6309 only code with no cpu switches in it.  That file(s) are 
nitros.asm and end.asm.  Missing totally from the level3 subdir, and 
according to locate, is not present in the mercurial clone at all.

But, I did find something that the coco can do but linux can't!
Pay attention to these screen scrapes:

{t2|08}/DD/NITROS9/6309L2/SCRIPTS:dir ../../../../../../nitros9

 Directory of ../../../../../../nitros9  2012/10/20 21:48 

6309L2          6309L3          3.2.9           COLORZAP.DSK    HRSDOS.os9 
DSKS            3.2.9a          dw3install      boottrack-gene  DW-stf 
dd.b09          DW3TREE         cmds.os9        OS9Gen          Cobbler 
dsave.out Directory of ../../../../../../nitros9  2012/10/20 21:48 
6309L2          6309L3          3.2.9           COLORZAP.DSK    HRSDOS.os9 
DSKS            3.2.9a          dw3install      boottrack-gene  DW-stf 
dd.b09          DW3TREE         cmds.os9        OS9Gen          Cobbler 
dsave.out

Count the backup levels in the prompt, then in the command line.

gene at coyote:/opt/nitros9/level3/coco3/modules$ ls 
../../../../../../../nitros9
ls: cannot access ../../../../../../../nitros9: No such file or directory

I am 5 levels up, but used 6 levels of backtracking.
Linux CAN do it one level at a time however.
gene at coyote:/opt/nitros9/level3/coco3/modules$ cd ..
gene at coyote:/opt/nitros9/level3/coco3$ cd ..
gene at coyote:/opt/nitros9/level3$ cd ..
gene at coyote:/opt/nitros9$ cd ..
gene at coyote:/opt$ cd ..
gene at coyote:/$ cd ..
gene at coyote:/$ cd ..
gene at coyote:/$ 

Go figure...  But it can sure break a nitros9 build script on a linux box.  
And I get to keep all the pieces. :)

Aha, found it. In linux, /opt is not the root of the filesystem.  So in 
order for that to work, you must also add the /opt to the path being 
accessed.

Like this:gene at coyote:/opt/nitros9/level3/coco3/modules$ ls 
../../../../../../../../../opt/nitros9
3rdparty  bootman  ChangeLog  defs  docs  level1  level2  level3  lib  
makefile  ReadMe  rules.mak  scripts  TODO

Works, but can that be used in a script?  I see no reason why not.
