sysinstall did this in its magic installFixupBase() routine as bogon #4. 
  I've no idea if bsdinstall replicates all the same post-install 
fixups.  Hmm, my fresh 9.0 system has no /compat or /usr/compat, so
this seems to be missing.  I think the package should keep installing
to /compat, but I don't really think the package should set the policy 
of symlinking /compat to /usr/compat.  That should be in the install if 
/compat doesn't already exist.

FWIW, for my own home-rolled installer on 8 I use the following shell
function to simulate installFixupBase() (note, the installed system is
mounted at /mnt, and this runs from the "outside" not in a chroot into 
/mnt):

# Fixups from installFixupBase() in sysinstall's install.c
install_fixups()
{

         chmod 0755 /mnt/etc
         mkdir -p /mnt/var/db
         touch /mnt/var/db/mountdtab
         chmod 0644 /mnt/var/db/mountdtab
         mkdir /mnt/usr/compat
         ln -s usr/compat /mnt/compat
         chroot /mnt /bin/sh -c newaliases
         mtree -deU -f /mnt/etc/mtree/BSD.root.dist -p /mnt
         mtree -deU -f /mnt/etc/mtree/BSD.var.dist -p /mnt/var
         mtree -deU -f /mnt/etc/mtree/BSD.usr.dist -p /mnt/usr
}
