It's a rough guess based on the likely compressability of the crash
dump, and the likely size of the kernel image.

dumpadm(1) has its own logic as to the minimum size of dump device it
will even attempt to configure.  I don't know how or if it and install
agree.  It would perhaps be reasonable to have install configure the
minimum size acceptable to dumpadm.
