This does not work as expected with in this situation :

   bash-5.1$ which slapos
   /usr/bin/slapos
   bash-5.1$ /usr/bin/which slapos
   /opt/slapgrid/d4af5a4bc0958cc5f60fac0dbf6c916e/bin/slapos
   bash-5.1$ ls -al /opt/slapgrid/d4af5a4bc0958cc5f60fac0dbf6c916e/bin/slapos
   -rwxr-x--- 1 slapsoft slapsoft 3492 Jan 31 10:01 /opt/slapgrid/d4af5a4bc0958cc5f60fac0dbf6c916e/bin/slapos
