[rescue] Solaris cp question

[Joshua D. Boyd]

I want to switch the disk that /usr is on.

If this were linux, I'd mount the new disk under /mnt/temp, then do
cp -av /usr/* /mnt/temp
then
mv /usr /usrold
then modify my /etc/fstab file to mount the disk on /usr.

Now, on solaris, I know how to edit my /etc/vfstab, but the copy step is
kicking my but.  I can't seem to identify a set of cp switches that
copies symlinks and pipes correctly while preserving the ACL.
