If you read the man page for update_dyld_shared_cache you will see that
you can run it with -root and the supply the path to the mounted volume. I
have done this in the past to solve similar issues in a restore situation
(there was some funkiness otherwise).
RTFM. Ouch. Yes, you're absolutely correct. I didn't see that
option. That might be a workable solution.
I'd still like to know, however, if the cache will automatically
rebuild itself or whether it has to be built manually on 10.6.
If you are worried about the version of update_dyld_shared_cache used,
then use the one from the target volume. Unless you have huge deltas in
the versions of MacOS X, you should be able to do this.
Big deltas aren't a problem; small ones might be. Big deltas
aren't an issue because you *can't* restore one major version of
the OS using another. Apple keeps changing the HFS format so
things like compressed extended attributes make it impossible to
write a bootable OS X 10.6 system using 10.5 (trust me, I've tried).
