I installed the rpm from the website and created a file root_fs by the following command
 
dd if=/dev/zero of=root_fs bs=$((1024*1024)) count=100
 
than I installed a file system by :
 
mke2fs root_fs
 
After that I trid to run linux with the following command line :
linux devfs=nomount
 
and I get the following message
 
VFS: Mounted root (ext2 filesystem) readonly.
Warning: unable to open an initial console.
Kernel panic: No init found.  Try passing init= option to kernel.
 
Does anyone know what's going on ?
