Various boot parameters can be considered in alternative GRUB 2 configurations.

But it seems that the shell script "init" from Knoppix does only support the
command line parameter "bootfrom" for the purpose of booting ISO images.

This one expects that the specified file name contains an "old style" device
name. Symbolic links (like "/dev/disk/by-id/scsi ...") which refer to better
predictable (persistent) device names are not provided at that point, are they?

Would you like to improve the support for other path specifications?
