That script, rc.sysinit is so big, but I will post it below.
I will check out the 2 distro and look at their boot script.
As for the bootloader of my build, I use GRUB. This is the one used in
the host, what I do is create a new partition, build my minimal system
over there and modify the grub.conf to pick up my build.
Any other suggestion?
Here is the rc.sysinit below, there are many error messages flashing
over the screen in booting, I add some "sleep 3" to the script and see
some errors like this,
"mount:mount point /proc does not exist"
