[BusyBox] Init Problem - Newbee Question

Thu Feb 13 10:45:06 UTC 2003

I just got through fixing this problem.  There could be several reasons
why this doesnt work.  For me, I am running everything in 'bochs' and I 
never got the initrd, ramdisk to work.  So that may be a problem.  I also 
never got lilo to work properly with a disk, (so if you are using a floppy 
boot disk), lilo seems funny with this approach.  So I went with 'grub' 
which worked a lot better for booting off the initrd.  Plus with grub it is 
easy to rebuild without messing up your main system.  Make sure you have 
ramdisk support in your kernel, I think in the menuconfig there is a option 
for initrd support also.  Now I havent tried this 100% but once I finish I 
might be able to help.  You can most stuff off the floppy in the beginning 
and then change your root(chroot) to a ramdisk.  And with this approach 
decompress a root directory from busybox as opposed to 'initrd'.  This is 
tricky. Say, root.tar.gz unzip to /dev/ram0, for example.

And last but not least you have to make sure that you have an /etc/inittab 
and also make sure you have login/getty from tinylogin or wherever.

Did I confuse you?
