first thank you for your answer.
you were wright as you wrote that I meant the "su" stuff. i thought it is for security reason or something
the root=LABEL=/ thing makes me crazy. i think it has to do with the initrd ramdisk and/or devlabel imho.
i have most modules compiled in the kernel, so i actually do not need a ramdisk( or should i use a ramdisk? - let me know
) i can boot the kernel when i change root=LABEL=/ in the fstab to /dev/hdx. but i would really want to know what is a) the advantage of a label and b) how can i set up a custom kernel which will boot with this option.
and what i also need to know is where the config for the module autoloading is?
i hope some experts can help me
