Yes, unlike other 4.3 systems, Sun 4.0 requires that the bootblock know
the location of the /boot binary.  From the installboot(8) manual page:

     The boot(8S) program is loaded from disk by  bootblock  code
     which resides in the bootblock area of a disk partition.  In
     order for the bootblock code to read the boot program  (usu-
     ally /boot) it is necessary for it to know the block numbers
     occupied by the boot  program.   Previous  versions  of  the
     bootblock  code  could  find  /boot by interpreting the file
     system on the partition from which it was being booted,  but
     this is no longer so.
