That's the Solaris _kernel_.  I don't believe that the same is true of
the Solaris userland.  That's done through some magic in `krtld' and
is designed specifically for dynamically loadable device drivers.
I'll have to go and dump the ELF headers on some drivers, but I don't
think that they make use of `.init' and `.fini' sections for this
functionality.  So I'd say you're comparing apples and oranges here.
