When did it even exist?  There should only be a requirement that the boot
loader is first on the disk (or slice).  On i386's, boot1 must be in the
first sector and boot2 soon after.  boot2 defaults to reading configuration
and booting from the 'a' partition, so you need a filesystem on the 'a'
partition of the boot drive unless you want to change this manually every
time, but the 'a' partition does not need to start at offset 0.

I sometimes boot manually from a non-default partition, and used to
always boot automatically from a non-default drive on one system (by
redirecting to the boot drive using /boot.config).
