Elting and most of all, Stephen P Richardson. If I left anyone off, I'm
sorry, it wasn't intentional (sounds kind of like and Oscar acceptance
speach :-)
Short answer. Can't do it with basic solaris tools (I'm not too surprized).
Medium answer. Get gnutar and eat up another megabyte or more of disk
space and still not have what I'm looking for.
Long answer (and the reason Stephen Richardson gets special thanks. He's
also the only one of the above who realized that what I really want to do
is flatten the directory tree during the extraction process). It would
appear that I might be able to use cpio to do it (although I haven't tried
it yet) since it has the ability to read tar files and rename the output
files "on the fly".
Longest answer. Either write my own tar that does what I want (shouldn't
be too bad given the wealth of tar packages available) or write/find a tool
that will edit the tar file itself (much scarier proposition).
At this point I'm leaning towards writing my own (specialized) tar, mostly
for the challenge of it.
The chroot option that several folks suggested won't work in my case since
the overall procedure that the extraction will be part of must be runnable
by normal users.
