Thanks.
But for what is that 10.5 and 10.6 subfolders in /EXTRA ?
I (will) not use that, becaue Chameleon should use that /EXTRA from active partition (Chameleon boot device menue not used) OR use , after selecting other boot device in Chameleon boot menue , that /EXTRA i selected in the boot menue .

So 10.5 / 10.6 subfolders may an SIGN, that Chameleon cant/does not reload /EXTRA stuff when selecting an different device for booting in the Chameleon main menue.
So maybe wrong /EXTRA content is used - that content from the active partition.
