I disagree, here -- only has to be /rescue:... at start time, inside init.

    /* after fork() */

	warn("execl of /bin/sh failed; trying /rescue/sh\n");

It's gross.  I'm sure someone else can write that better.

No, the system will go

    rcrt0.o: ld.so failed /* or something like that */
    Enter full pathname of shell, or RETURN for /bin/sh:

# One question here:

Bigger question:  Why did Solaris bother offering a separation of /
and /usr when / by itself is nigh useless under Solaris?  More to the
point, why did Solaris (SunOS 4, really) make it necessary to have /
and /usr mounted in single-user mode?

But we digress...
