i've been trying to merge two different knoppix versions, namely 402 and 501, on a single multi-boot dvd. i've rebased root directories on the dvd for each distribution to a separate unique one and tried booting with an apropriate 'knoppix_dir' parameter at the isolinux prompt. 402 boots sucessfully, but 501 fails. i've tracked down the problem to "cloop.ko" module loading section in the linuxrc startup script. when enumerating devices in search of the cdrom media the 'FOUND_KNOPPIX' variable gets properly set pointing to '/dev/hdc' but then is reset upon failure to load 'cloop.ko'. the 'module_dirs' variable is not 'knoppix_dir' dependant and since the cloop module for 501 has been moved out of the initrd filesystem it fails to find the module file. was it in any way intentional or is more of a bug ?
