You mean same behaviour as can be reached by "cd /home/peter/usbstick" 
"./olr"? This would (now, as OLR moves from open to openat due to lack 
of kernel open support on modern architectures) be easy to implement.

To have ideas, one would need to know the problem first. Another 
possibility obviously would be to define "SYS:" or whatever to be an 
alias for a linux directory like "FileTools.SetDirectory SYS: 
/home/peter/usbstick~". However, such a change would need to solve the 
original problem better than symbolic links.
