Command line variables

What about a new command line variables autoyast=cdrom:/<path> ? It seems, that autoyast suse 8.2 isnt recognising, that it was booting from an self-made cdrom. it doesnt looks for the config file specified with autoyast=file:/<path> on the booted cdrom. only autoyast=device://<device>/<file> is another solution, but how can we set the bootcdrom <device> automaticaly on the fly? -- MFG Steve Schneider
