no it does not ...
- you can simulate a missing disk ( at least the missing MBR )
to see if it boots the other disk
dd if=/dev/null of=/dev/hda bs=448 count=1
- if it doesn't boot... you never had raid properly configured anyway
- to do booting tests ( lilo or grub or syslinu or ?? ) reqwuires you or
somebody have phyical access to the machine in case thngs go bonkers
- if you do not have physical access, one assume you know what you

the warning is exactly correct...
- if you install on /dev/hdb or /dev/hdc .. etc.e.tc..
it will warn you if the system has /dev/hda
- trying to read MORE into the error messages is a bad idea
lilo and grubs error messages can all be cleaned up .. if you wanna fix
error messages .. and internationalize it too so that someone else
doesnt need to fix it again later

so there is NO bug to be reported. ... as it is correct that the disk
referenced by lilo.conf is in fact a correct warning

it is precisely accurate .... its NOT the first disk

lilo NEVER overides lilo.conf settings
an incorrectly defined lilo.conf will screw up your system and render
it non-bootable ... or incrorect kernels or incorrect initrd or any
other gazillion factors.. NOTHING to do with lilo rendering it unbootable
though some problems is a lilo or grub problem, those are far and few
no system error messages will (correctly) tell you if the system can boot
after you ran lilo or grub or any other loader..
- you are just forced to (re)boot and see
