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

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:

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?
