It sure can.
When you boot -a to /rescue/init, it uses /rescue/sh instead of /bin/sh,
and sets up /rescue at the start of the $PATH, so things should "just work"
even if /libexec/ld.elf_so or /lib/libc.so.12 is hosed.
This is precisely the reason why I invented /rescue and why I made
the enhancements to the kernel's RB_ASKNAME (boot -a) operation.
(I think there's a couple of places where the /rescue tools haven't
been fully converted to using /rescue instead of /usr/bin (et al);
we should chase up some changes that FreeBSD made when they borrowed
the /rescue concept from us in NetBSD.)
