    [Bug ?!] Initrd and Linuxrc

    Hi!
    I have a little question about booting of knoppix...
    Well, start with theory of booting with Initrd:
    - kernel load into memory initrd image
    - decompress it
    - execute LINUXRC (yes, must be an executable or shell file called linuxrc )
    - after that or linuxrc call /sbin/init or it's called automatically, otherwise kernel panic

    Pratically
    - knoppix put in boot command line a line like init=/etc/init
    After many test that I do, I see the param init (in this case /etc/init) it's execute only if present another param like root=/dev/ram0
    I see /etc/init in INITRD of knoppix contain a small script like
    Code:
    /linuxrc
    exec /sbin/init < /dev/console > /dev/console ...

    I think that script and relative boot parameter is useless, infact knoppix boot correctly without "init" file in /etc and without bootparam "init=/etc/init".

    But..my question is: if it's useless, why is still present?
    I'm forgot something?

    Cheers

    I read that knoppix can use INITRAMFS..But minirt.gz isn't an archive of INITRAMFS

    Confirmed. Knoppix 4.0.2 will boot just fine without the "init=..."
    But..my question is: if it's useless, why is still present?

    Probably a vestige. Naturally, you're free to take in out in your own remasters.
