FWIW
I don't use boot floppy and successfully run two root filesystems
in my case two different versions of rhat 5.2
What follows is how I would set up your config :
I would change above to following /pair/ of lilo.conf
(I don't show your preamble, the 6.1-orig stanza, or the win95 stanza)
1)for use when booted up in rh6.1
image=/boot/vmlinuz-2.2.14
label=linux
read-only
root=/dev/hdc2 ### /dev/hdc2 is mounted on /
image=/rh5.2/boot/vmlinuz-2.2.14
### /rh5.2 is where redhat5.2 rootfs is mounted when bootedin rhat6.1
label=rh52
root=/dev/hda3 ### /dev/hda3 is mounted on /rh5.2
read-only
-----
2)for use when booted up in rh5.2
image=/rh6.1/boot/vmlinuz-2.2.14
### /rh6.1 is where redhat6.1 rootfs is mounted when bootedin rhat5.2
label=linux
read-only
root=/dev/hdc2 ### /dev/hdc2 is mounted on /rh6.1
image=/boot/vmlinuz-2.2.14
label=rh52
root=/dev/hda3 ### /dev/hda3 is mounted on /
read-only
----
this type of dual rootfs setup works for me,
in my case two versions of redhat5.2
for one of my rootfs /boot resides under /
and for the other rootfs /boot resides outside of /,
similar to your case and no trouble results.
I don't need to use a bootfloppy
lilo can be run (if necessary, or just for fun 8~) )
when booted up in either 5.2 or 6.1
In this method I do have to keep parallel lilo.conf
and also two fstab
one under /rh6.1/etc and the other under /rh5.2/etc
but this is not hard to keep consistent with any future changes.
at any give time
one or the other of the two rootfs is mounted as /
with the other mounted under a directory with its identifying label
once working,
the rootfs that isn't being used as /
doesnt have to be mounted at all,
unless you want it mounted to be accessible for examination
or wanting to rerun lilo , ...
this way the other rootfs has some degree of protection
