Forgive my slowness to understand your suggestion. The kernel I built
has all the sata drivers, usb drivers, and scsi layer built in. So
during the kernel bootup before the root is mounted, all drives (sata
and usb) are scanned and detected. How does an initrd plus mounting
the root filesystem by UUID or label help here? Or how can I set the
"root" in the lilo.conf?

If an initrd is used, I would rather go with option 3. That is, build
SATA drivers as loadable modules and load them in the initrd. Then
before initrd loads sata drivers, there is only one usb drive as

Also I'm lost by this comment: "though without special scripts of your
own". Could you explain it in another way? Were you saying that I need
my own special scripts to mount the root filesystem by UUID or label?
I think this is quite obvious since I need to build an initrd, which
is always customized. :-P
