I don't know lilo's "emergency" command, but lilo (and grub) is not in
the position to do want you want. Maybe lilo has some shortcuts to
instruct the _kernel_ to do so. This is usually done via kernel
command line arguments (you can see them in /proc/cmdline).
You can do the same with grub. Provide "single" as an argument to boot
in single user mode. And give "ro" to the kernel to mount root
read-only (but that's done often as default).
So, load the kernel this way:
kernel /somewhere/mykernel single ro root=/dev/rootpartition
Note that options to boot in single user mode get interpreted by
/sbin/init, so in reality bypassing the kernel.
See man-page "bootparam" or other sources for information about kernel
parameters...
Bye,
Robert
