root cd : init not found
Hello
I am trying to make my own root cd for learning purpose.
I have made a floppy with a kernel 2.6.15 and I try to boot the cd but it fails ...
However I have tried to make a root floppy and it succeded (butnot enough tools where available due to size).
the message following the root filesystem mounted are:
VFS: Mounted root (iso9660 filesystem) readonly.
Freeing unused kernel memory: 212k freed
failed to execute /sbin/init. Attempting defaults ...
Kernel panic ....
on the floppy
---------------------
in /boot/grub/menu.lst
....
title Debian GNU/Linux, kernel 2.6.15
root (fd0)
kernel /boot/bzImage init=/sbin/init root=/dev/hdc ro single ramdisk_start=0 load_ramdisk=1
prompt_ramdisk=1
pause CAUTION INSERT CDROM NOW
savedefault
boot
....
on the cdrom
--------------------
all devices needed are present (/dev/hdc, /dev/ram0 ...)
all librairies needed too
in /etc/fstab :
/dev/hdc / iso9660 ro,exec,auto 0 0
#no proc filesystem is used (do I need it ?)
....
If I have understood (which is not sure :) ... with the menu.lst of grub, a ramdisk should be mounted (thanks to the cd) ...and here is probably the problem !!!
CAN a RAMDISK be created thanks to an iso9660 image ... or must it be a gzip (of ext2) or ext2 filesystem ?
Do I need initrd ? I suppose not cause kernel can mount a ramdisk itself
Once I get through that difficult (for me) stage, the init program will be executed and it will among others things mount the cdrom as root (inittab)
Can someone help
me ?
Thanks
PS: I know that having a root filesystem mounted readonly is not the idea of the century :)
