Ooops... Looks like a crashed root fs. (That occasionally happens when a system
goes down without unmounting read/write file systems properly.)
"init" is in /sbin or something like that (might differ between distros), and it
might be that the file is missing or damaged, or that the kernel somehow cannot
find it after booting up. You need to fix it somehow; alternatives
1) Do it manually by mounting the disk from a running Linux system (working dual
boot, some other machine, boot/rescue floppy/CD or whatever) and restore the
damaged files, fix thrashed permission flags or owner data, or whatever
causes the problem. It might be that the "executable" flags have been reset
or something like that. If the file is gone or damaged, you'll need the
packages from the distro CD, or wherever you installed your system from.
2) A shortcut might be to boot up from the distro CD (providing you installed
your system from one!), and tell it to install only the basic system
executables and libraries. (I think most distros have "init" and related
tools as a separate package...)
I'm not sure about others, but IIRC, if you tell a Red Hat distro to do a
system upgrade, it will install/upgrade what you tell it to, and also install
and set up the boot loader, so that your system will at least boot by itself
again.
Your config files will be backed up with extensions like .rpmsave, so that
you can restore your old environment easily. Most importantly, it's lilo.conf
you need to restore (don't forget to run lilo afterwards) to get it to load
your RTL kernel. (Unless that's the default kernel for your distro, of
course!)
